He is a masochist, that's it. That must be it or else he is just plain crazy, going thought all of this once again do not make you a normal person. A normal person would a real and functional relationship with someone around their own age. But no he was a stupid man with 30 years who was once again getting laid with his younger sister's best friend, who happen to be only 18, but no that was not the worst part, he was IN LOVE, yes fucking in love, with that girl and she would only fuck him 'cause she's was hurt, sad and had a fight with her boyfriend, who happens to be the other best friend of his sister. And the next day when they would make up in an mushy way live on their webshow he would be miserable the whole night thinking about her hair, her eyes, her body laying against him and how he missed her so much even yet she was just upstairs on Carly's room. He could make her happy, they could get thought their age difference, his sister, his father, her mother but that were one thing they could not get pass the fact that she loved her lame boyfriend even though he clearly didn't have he wasn't mature enough to deal with her. Yeah, he love her but she just want to fuck him, she just want him to be a rebound, to make her forget her problems for one night, maybe two, but she didn't loved him, and with that he was left once again laying alone in his bed staring at the ceiling thinking about her and when would be the next time she come. He shouldn't want her to come back, to make him suffer once again but he wants it, 'cause he was a masochist. That was it. He was not crazy, not hopeless in love he just like it to suffer a lot.
