I know i already have a story where I dealt with the after affects of Jean Valjeans death (Find a way to help her Marius), but that was more musical based whereas I feel this story is more novel based.

Valjeans Ghost

Several weeks had passed since her papas death and Cosette was in her bedroom trying to read a book, she couldn't concentrate on the pages though as her mind kept drifting to other things. She hadn't been feeling like herself since her papa died, she felt like she had gone through every single emotion there was, she would feel intense anger and desperate sadness and she could turn from one to the other in a split second. She was getting very tired of it, she so desperately wanted just to be happy again and enjoy her life.

She gave up on her book and put it to one side, she sighed and looked towards the clock on the nightstand, it wasn't very late yet and Marius would probably be coming to bed soon after he finished working in his study.
She had been feeling very torn apart inside when it came to her husband recently, since finding out the reasons why her father had been so distant towards her before he died and knowing the part Marius played in his death she couldn't help feel a little resentful of him. She still loved him totally and completely but he had almost let her father die without her seeing him again and that was going to take time to heal. She had been acting very distant towards her husband lately; it was her way of punishing him unconsciously for how he'd treated her father, and she did want to punish him. "Why did he think he had to protect me from my own father" she thought to herself that night, "If he had acted differently towards my papa he would still be alive now and he would be living with us.

Cosette and Marius hadn't really been connecting with each other lately, they would speak to each other but they couldn't really talk to each other anymore it seemed, Cosette couldn't even enjoy silence with her husband anymore like she used to, her mind would just drift to how Marius had treated her father and she found herself having to leave his side lest she go crazy with anger and grief because of what he did.
Marius had been trying to make amends, he had apologised numerous times and explained to Cosette why he had thought her father was dangerous and why he felt he had to act the way he did towards him, as if that would somehow make it all better, he had also surprised Cosette with some lovely flowers the previous week to cheer her up. She liked flowers and Cosette had accepted his gift with a smile and she thanked him like the good wife she wanted to be, but it hadn't made her feel any better inside, and she still continued to act cold towards her husband.

Other things had changed too, she and Marius had only made love once since her papas' funeral and even that had failed to excite her like it used to. Somehow a few nights ago they had started kissing and one thing led to another and eventually they were undressed together. But Cosette paid little attention to Marius's soft kisses and touches that night or even his gentle whispers, she didn't hold on to him whilst he moved inside her, she just laid her arms over her head and held onto a pillow until Marius was finished. She didn't even reach climax that night, which only disappointed her further because she had really come to enjoy that part of married life. It wasn't an entirely unpleasant experience though, it's not like she felt violated by him at all, there was just no fire or passion between them that night like there used to be and she could tell Marius felt it too. He didn't say anything to her after they were finished; he just kissed her lips tenderly and put his night-clothes back on and they were both soon fast asleep afterwards.
They had only been married a few months, "Was the thrill gone already?" She thought bitterly.

Cosette knew she would forgive Marius eventually, she already had inside she just hadn't told him so yet. "Perhaps it was time I did" she thought to herself; she was tired of living like this and it wasn't right to keep pushing him away like she was doing. "I love him, and I need to tell him that" She thought.

Cosette tossed the blankets aside and put on her dressing gown, she took one of the oil lamps from the nightstand and then she made her way downstairs towards Marius's study where he would no doubt be either working or brooding, most likely the latter. Cosette reached his door and was about to knock but she felt herself lose her nerve and she backed away. Something else came into her mind and she walked away from the study, instead of going to her husband that night she found herself heading to that small cold room where her father would meet her after she had been married.

She let herself into the room and looked around, someone had neglected to shut the curtains and moonlight was pouring into the room filling it with a faint blue glow, she looked around sadly for a moment and remembered those few sombre times her papa came to see her after she had been married. "Why did he act so strange towards me?" she thought "I wouldn't have forgotten about him when I was married, why couldn't he live with us?"
Cosette set her lamp on a table and sat down in the chair her father had used in a vain attempt to feel close to him again. It didn't work though; she just sat in that cold dusty room and felt even worse. "Why had the most important people to me lied to me?" She thought to herself, "Why did they think I couldn't handle the truth?" Cosette felt incredibly sad at that moment sitting all alone in that room, she closed her eyes and placed her head in one of her hands and silently shed a few tears for everything that had happened over the past few weeks.

Then suddenly she heard a voice say her name, it was a familiar comforting voice that filled her with warmth inside, she snapped her head upright as she heard the voice again and there he was, standing in front of her clear as day and smiling lovingly at her like he'd never even been gone from the world.

Cosette sat frozen in shock as she looked upon the smiling face of her dear father who had so recently been taken from her.

"Hello Cosette" Jean Valjean said tenderly.
