1 month.

Meredith walked to the front door. She knew who it was so she just threw the door open. Asher came running in, his arm clutched tightly around a new dump truck. Mark stood at the door, shifting his weight from foot to foot and looking at the ground. Despite the fact that Meredith was letting him see Asher they had yet to have a civilized conversation. "Thanks for bringing him back," she said grabbing the door to slam it shut.

He caught the door and looked into her eyes saying "Mer, can we talk?"

She resisted the urge to melt because of his look and stated back coldly, "I am not doing this with Asher here."

Mark shook his head in agreement, but his eyes went back to the floor. Meredith couldn't believe she had said it until it was out "why don't you come by tomorrow after I get off work, I will get Derek to watch him."

She watched as his head snapped back up and he nodded his head vigorously before turning to leave.

The next day after she got off work, she walked into Derek's office, "are you sure you can watch him tonight?" she questioned hoping he would say no. No such luck. He practically pushed her out the door.

When she got back to the house she called Mark to let him know she was there and then waited for him. She had almost started to doze off when he knocked on the door letting him in she lead the way to living room and sat in a chair while he occupied the couch. A silence fell neither one of them knowing what to say. Finally Mark spoke "Mer, I miss you and I don't want to lose you."

"You should have thought of that before you took a shower with my best friend," she said sharply, adding more quietly "but I guess I should have known this would happen when I married the resident manwhore."

Mark looked at her before he spoke again, standing up and beginning to pace in front of the couch "I swear, it wasn't what it looked like, I got there, and you remember Asher wasn't feeling well so Jaime was watching him that day, I asked her to stay while I took a shower so that if he woke up someone would be there and then right before I got out of the shower she got in with me, I thought it was you and turned around and that is when you walked in."

"Mark, I just don't think I should believe you, I don't have any reason to," she said back softer than when she spoke before.

"Mer I have never been unfaithful to you, not even when we were dating," he spoke quietly "I love you." He spoke again as tears began to spill from his eyes "I got a job as head of plastics at Seattle Grace, I want you back, but even if you don't want me I am going to be here for my son."

Tears were falling down Meredith's face too at this point, but she managed to gasp out "Mark, I'm three months pregnant."
