Boyfriend cheating

I made a post a few weeks ago about my boyfriend cheating and my mom saying i should come home. Safe to say everyone was right and he did it yet again. Found his phone this morning open to a snapchat account that was his hookup account. He told me he deleted it last February when we argued about it then. I am so broken and any encouragement would be great. I am moving my stuff out Tuesday, today is Sunday. We work at the same place which really blows. My birthday is Thursday so im probably doing nothing tbh.
