Kind Of Long But Please Help 😭

*Please excuse the bad grammar*

Me and this guy have been on and off for the past two years ( I was the one breaking it off because I wasn’t sure about the future of our relationship) . Anyways we recently got back together about 3 weeks ago and it’s been great.. or so I thought 😬. He left his phone with me while he went to take care of business and of course 🤷🏽‍♀️ I went through. ( Curiosity is a bitch ) . I found out he was still texting the females he was messing with while we taking a break, and I semi-confronted him about it. I forgave him but I can’t help but think he’s still doing his own thing. He keeps telling me that he cut them off and gets agitated when I don’t believe him or tell him that he can continue to do “him”. I’m nothing compared to what he used to have and he tells me he likes me the way I am , but I feel like that’s a lie 🤦🏾‍♀️. I want to stay with him and get passed this whole thing but idk how ! Please help 🥺
