Advice Please

So to put a long story short, hopefully, me and my boyfriend of 3 years are breaking up, hopefully. He's done/said a lot of things that make me resent and almost hate him! There's been too many last straws but I feel like this time he actually heard me! He's been staying at his mom's house, 1 state over, where he works, he said it's to save gas money but I know it's to be away from me. However, during a conversation while he was there I told him I'm packing his stuff and haven't spoken to him since. This was Tuesday, now today he comes home....I definitely don't want to see him, nor did I even pack his stuff... but idk what to do, act, say...? Also my 2 kids will be here AND although I do want him to leave I know I can't afford this house on my own... Any positive advice is grately appreciated - please and thank you!
