Confusing Situation

So long story short: the guy I've been seeing for two months just found out his ex-girlfriend is three months pregnant.

They had ended on mutual yet poor terms and she has been trying to get back together with him ever since.

I told him he needs to do what's best for him regardless, and that he shouldn't worry about me. He doesn't want to start a relationship back up with her, but he's not going to leave her because it's still his kid.
He still wants to keep seeing me but I'm not sure if that's the best solution.

I mean. Yes, I really enjoy being with him and I have pretty strong feelings for him but..if he has a possibility at this being a family I should step aside.

He's completely lost right now, and that's understandable considering he just found out about this not two days ago. (and I this morning.) I just want him to be happy is all. No matter what the outcome may be. Still, there's a small part of me that wants to just keep pursuing him. Is that even remotely okay? I don't know.

Advice, or thoughts would be appreciated.

It's better to come from a broken home than to live in one.

That's something I finally came to grips with, with my ex. We co-habited but were not in a relationship for pretty much all 6 of his years. We hadn't shared a bed since he was an infant, we were at best barely civil to each other, and at worst screaming the worst filth at each other. In the end I realized that what we were teaching him about relationships were all the wrong things.

Your BF is better off not getting back with his ex, with or without you.

Thanks, that is really helpful. It definitely puts a perspective onto things.
