Any Advice please!!

Hey there, I need to let go of my Husband for 7yrs. Things have been really hard for the last 4 yrs.

It’s been really crazy and TOXiC. It’s not a healthy relationship we have 4yr old baby girl. But I think we both have come END! But I have a hard time meeting it to. Like I won’t eat, yes I’ll cry but it’s on and off type thing. He is will be traveling pretty soon but he will not be coming back basically the whole be the end of our relationship witch it has been he’s idea since I know him he’s from mx but he don’t wanna be in USA anymore. So over the weekend we had an argument the it killed it I think. -he’s the type of guy the likes exercising a lot I’ve been trying to go with him but he just won’t take me. I’ve seen selfies of him when he’s at the gym and he will post them. And some on he’s other social

Media where he has he’s shirt off. So the made me soo mad the day. He txted after work and said “ To get ready we were gonna go to the gym.” I didn’t see the msgs until o got home. But I told him okay let’s go. We both agreed we were gonna go after dinner. But I also told him I want to go clubbing he said okay. we were getting ready to go to the gym but he’s response immediately was the if I go with him then we won’t go clubbing too. I said oh it’s okay we can go the next day. He said no! If you come then we not going to no clubbing. And GILRS the turn me into a monster I was acting up bad. Short story: I need an advice on how to get over him?
