He's so nice to me 🙃

Back story: we've been officially broken up since December. We "broke up" when I was 7 months pregnant because he cheated on me and told me he didn't love me, stupid me got back together with him after having our son because I thought it was the right thing to do but quickly realized that I was not happy so I completely ended things. Since December he has not tried one time to get our family back together until now. Now he thinks he can just come back and everything will be peachy but life doesn't work that way and he's not happy about it. I'm determined to stick up for myself this time around and stick with it!
