<human>: Here's the deal, I'm a 22-year old single mom (my daughter is 2 months old) and I've recently fallen really hard for this 20-year old man. Everything would be fantastic except for a couple of tiny details.

1) He used to be my ex-fiance's best friend.

and

2) He is conflicted between me and an ex-girlfriend of his.

Basically, my relationship with my ex had been slowly deteriorating over a manner of months and he and I recently realized that there just wasn't anything there anymore compelling us to be together. That ended, slightly messily, but not terribly.

This guy--Alex--that I've fallen for has been out of the relationship with his ex for 3 months, but still has some feelings for her. They started talking shortly after he and I really became friends, about a month ago.

When my ex and I began the process of separating--while trying to work out custody of our daughter--Alex stepped up and was there for me and Allison, helping us stay sane and reassuring me that there was no shame in the separation.

Alex and I both have feelings for each other... These feelings led to some pretty wonderful interactions (see my post in /r/sexystories).

He's the most wonderful and romantic guy I've ever met and I've fallen really, really hard.

But I feel like if I try to pursue these feelings too much then I'm going to mess things up with him talking to his ex. And I'm not sure if it's me he wants to end up with or her, but all I want is for him to be happy.

He knows exactly how I feel and everything is out in the open between us.

Now what?

Can you condense the text into a few key points?
<bot>: I really like this guy and I don't want to mess things up, but I don't want to give him up, either.
