Thank you for all the feedback!
I went and saw a lawyer yesterday. He said my AH would have to pay for child support and alimony for me. I am currently a SAHM.
I can clearly see what he is doing to me. And I know I want better for my life. I am clouded by my emotions right now and having a hard time handling them.
I told him about visiting a lawyer, and he continued to tell me it's the best thing that can happen. How he has had the best few days away from us.
With all this, he visited his daughter on Tuesday. And will probably see her on Sunday. He is good to her and wants what's best for her.
In my head, it's hard for me to know/understand what made him switch all of a sudden. I mean, he has left in the past but only for a few days, and he was obviously wanting to come back. Now it is like he REALLY doesn't love me anymore, wasn't ever happy and just doesn't want to be with me anymore. And that hurts. I feel like this is true.
