We're going to be ok right? I keep telling myself that, my children's father I am seeing on FB has went back to his second BM. And they supposedly gotten married????

I'm not sure how I feel, we've always been on and off and he has never had a job. He's 33 he has two older boys he never sees and now my two that he won't be around. So why am I letting this bother me? I want better for myself right? Just shocked I guess.
