I have a 6 month old with a guy I only dated for two months (everything changed when I got pregnant but that's besides the point)

So my daughter's father already has a son from a previous gf who he had dated for 7-8 years (his son is 5)

He makes every effort for his son. Has all the time in the world for him. But my daughter doesn't get the same treatment. Sure we aren't together. And he isn't with his ex. But they share 50/50. He is actively involved in his son's life. But there's always an excuse or he's always running late for my daughter whether he has two weeks notice or two hours notice. Doesn't matter if we plan stuff or not.

For instance, if we're supposed to connect after work, he always is stuck in traffic or his boss asks him to stay late or something. (Yes I know traffic is a reasonable excuse. But when he has his son or has to pick him up after work, he is always on time -- I know this because the pick up time is 5:30 and at 5:30 the building closes. You can't be late for child pick up) But if it's my daughter, he doesn't show up until 8 or 9 PM. Because traffic. Traffic always hits when he's supposed to spend time with her.

But if i happen to be busy on one night during the week, he freaks and accuses me of withholding his child from him. When I'm not. And i always give him notice. I'll let him know that next week I have dinner plans on Thursday night. And he'll be like well Thursday was the only day I was free.

Shes 6 months old and has probably seen her dad 10 times. And no that's not a lot. Sorry but it isn't. It's not like he lives five hours away. He's 30 minutes away.

Also just an added note, when I found out I was pregnant I was considering moving further away because rent was cheaper and it would be more affordable for me and he insisted that I don't move because he didn't want to be that dad who never sees his kid and wanted to be close to his baby. I respected that.

But now here we are and I can't be bothered to make an effort. Am I selfish? Because now I don't text him. I don't try and make plans. I don't ask when he's free because if he wants to make the time then he can text or call me and make it work. If he doesn't say anything I'm not bothering. Thoughts?
