My bd left and now wants to come back

Okay so a few weeks ago my bd left after an argument and has not returned home or contacted me. He told my mom he has no money for gas atm so he’s sleeping at his parents and he’ll come home in half a month when he gets money. He totally just left us and hasn’t asked about his kids till my mom reached out. He told my mom he’s coming back home it’s just things have been tough. But he hasn’t even contacted me like he usually does. My guess is he wants his freedom. He told my mom he’s going to text me in a week to let me know what’s going on but I’m like I don’t wanna talk to him I’m just done. I feel like if he wants to contact about our kids he can go through my mom. I’m just like each time we talk he’s always coming up w bullshit excuses, trying to argue and make me feel crazy. It’s been a free week since he’s been gone I assumed we are over bc he never replied to me. So he’s trying to call shots thinking I’ll just take him back ? I guess that’s what you get when you give so many chances lol. Well this past week I been crying in the darkest places ever I lost 5lbs I haven’t been eating right. Just the other day I felt a little better bc my sisters came over and we talked about it all. It’s just dumb to go back to a toxic relationship after I’m already healing myself. I just want him to know he can’t ever make me feel like less then a person ever again
