My boyfriend from 7th grade

We dated from 12-15 and then again from 18-19 broke up when I joined the military. We haven’t spoken but I check his Facebook often and turns out he’s been checking mine too. He messaged me last week to see how I’ve been turns out he’s getting a divorce because he never loved his wife and told me he’s still in love with me to this day. And honestly I think I feel the same way I’ve thought about him constantly since I met him at 12. I’ve never had any feelings as strong as I did for him until I met my husband. My husband is verbally abusive and just lives off me I pay all the bills I bought the house he calls me the r word and the b word daily. Tells me how stupid I am and hardly spends time with me. I’ve been thinking of leaving him for a while but every time I get close to leaving it seems he does something that makes me think he’ll change. I feel terrible for feeling this way and I don’t know what to do. I do love my husband but I’m not sure I’m in love with him plus we’ve had issues since the beginning like he lied to me about being married when we first met and cheated on me while I was over seas but said he felt pressured to sleep with her. I don’t know if I need advice but I needed to get this off my chest. I don’t know what to do
