Coworker Crush!

Ok ladies, this one is a bit of a doozy, so stay with me

My ex and I just broke up, but i am about a month pregnant with his baby. A little while after we broke up, I slept with one of my coworkers. It was amazing btw, like wowza.

Anyway, things at work are a bit tense now, as in him and I don't talk much anymore except through Facebook, and even those convos are short and don't really have much depth.

But at work I always catch myself staring at him and remembering the amazing night we shared. I want to bring up to him that I want more, not necessarily a relationship, but a friendship and maybe lead into more, but idk how.

Also he knows I'm pregnant, and idk if maybe that's a turn off? Any advice is greatly appreciated. Thanks guys!
