Finding real love after a divorce...

Birdie • Taking life one day at a time.
...seems to be the scariest thing I have ever experienced. I tried so hard to find love in the two men I dated since my divorce 3.5 years ago.  It wasn't there. So I quit looking/gave up.  Spent 3 solid months alone and chilling with my girls. It was great. Then I met a man who changed me life. We fell in love.  We've been together 7 months now. Two months into it, this girl he had a "fling" (his words)  with BEFORE ME (he didn't cheat) called and said she was 15 weeks pregnant. We went through ups and downs, but we're still holding on to each other. Well, she's due this month and I'm terrfied. My emotions are all over the place.  We've been looking for apartments together (for when my current lease is up) for a few weeks now, but I'm scared it would be the wrong move. Any advice?
