Thinking about my ex

I'm happily married, pregnant with 2nd child but can't help but think of my ex from time to time. We had a good relationship, aside from he lived across the country and he was very controlling. He found out shortly after we got together that this girl he was sleeping with got pregnant, turned out the kid was his..

This is not the reason I left him, considering I had a kid from a very past relationship, the reason was because I knew he wouldn't be able to leave his daughter once he got to know her. The last few months of our relationship he was spending a lot more time with her event hough she was an infant and I knew he was growing attached. He had plans to move to be with me, and I knew he wouldn't want to.. And there isn't a way for me and my son to pack up and move across the country.

So when I explained everything to him and ended it, he called me a cheating deceiving conniving slut. (even though I had been totally faithful for 2yrs long distance). So wasn't 100% upset over it..

But I just recently seen he's creeped my IG and FB because he's accidentally or intentionally liked a picture and then unliked it..
