I caught him cheated but he was cheating with me

Been dating this guy a couple months and we live 2 hours away from each other so we see each other on the weekends . Well this past weekend I went up to surprise him by going up there Friday instead of Saturday and he was shocked to see me like what are u doing here shocked he didn’t want me on him or anything and kept being on his phone and even dipped off for a few minutes. Within the hour someone knocked on his door and he told me not to answer it but then they started banging . Saying ____i know you’re in there your cars out front open up. So I’m like who’s that and hes like his moms church friend that checks on him I’m like ok so why we hiding ? (He had pushed me into the kitchen away from the windows ) and something just wasn’t right so I opened the door “to go to my car” and the girl was like who tf are you ? And I’m like nah who are you? And she pushed past me and the dude wasn’t in the kitchen anymore . She’s yelling looking for him and stuff till she find him she’s hitting on him and stuff asking who I am blah blah and when I walk in she’s like I don’t have a problem with you you can go and I’m like huh? I’m his gf . Think a she was the side . She’s like girlfriend? aww that’s cute I’m his fiancé . And flashed her ring and said Now get your stuff and leave . The dude was just there quiet . I looked at him before I walked out and just shook my head . I got in my car and cried . I hadn’t talked to him since that Friday but he started blowing me up Monday and a few minutes ago he said he’s on his way cuz he needs to talk to me . So ...what do I do? I don’t want to be with him and I told him not to come but he’s coming anyways . Should I just hide inside like he did or hear him out but still not talk to him or what ?
