<human>: She doesn't want to make things work, I do. I made a thread earlier this week about things,  but it gave me a lot of perspective and I warmed up to the idea of having a family together. She wants nothing to do with that, but still wants to have the baby. 

It's been a week, and she's already sleeping with other men and on dating sites while being pregnant with my baby. It's broken me down mentally and I don't know how to deal. 

How do I move on from someone I love when I am going to be attached to them for the rest of my life now? Especially over this next year or two when we'll be forced to interact a lot.

It seems like the general consensus is that a lot of women, especially around my age, really don't want to deal with the baggage of dating a single father. Not only that, but I'm not even sure I'll have time to date between raising a kid and going to school. 

Do I just stand by on the sidelines for the next few years while I watch the woman I loved date other men?

Give me the gist of the text in a nutshell
