Fight or Flight reflexes are in full effect.. What do i do :(

So I’ve been talking to this guy for 3/4 months now. He told me pretty early on he gets to know one girl at a time so he wasn’t really talking to any other girls, but we haven’t had the “let’s be exclusive or official” talk yet! It’s still pretty early but we do see each other every week and sometimes multiple times a week and so far he’s been like my dream guy. His consistency and effort is truly unmatched and he’s very much so turned into my best friend I tell everything to. However.. in the very beginning one time he started to say my name but it started coming out as another girls name (starting with a m) before he caught himself and corrected it. I didn’t really dwell on it because it had only been a couple weeks at that point. Fast forward to last night, he accidentally called me another girls name when we were talking. To be fair the name is only one letter off from mine (ex. Kaley, Haley, Bailey).. it definitely annoyed me😅 Of course he apologized and long story short, reassured me he was not getting to know other girls and he knows a lot of girls with her name so it was just a mistake.. Again, annoyed me 1000% but tbh when I get mad my baby daddy’s name wants to come out🙄😂 so I chose to let it go. So today🙃 we were in the car and I was on his phone picking songs (I’ve never been on his phone other to look at things he shows me or to play music in the car).. so I decided it would be safe to look through his pictures. BOOM.. he had a whole album titled the girls name he accidentally called me last night with pictures of her in it. Granted, the last picture that was added in that album was from October of 2023.. next thing I know I’m clicking on his Snapchat.. she’s also on his best friends list along with his other ex (the girls name that starts with an m he almost called me the first time). He told me him and ex w an M have been broken up for 3 years and they stayed friends so they talk occasionally (I do believe this but still annoyed by it) and he ended up telling me him and the girls name that rhymes w mine ended as friends as well so they also talk. He ended up deleting them off of his Snapchat as well as a bunch of other female friends to prove a point that he didn’t care.. honestly. It does sting a bit but the part that hurts the most is the dishonesty😞 He may not be straight lying but he definitely didn’t tell me last night that he accidentally called me that name because he used to talk to a girl and still does with that name.. he left it as he works with a girl with that name. I dealt with lying in my previous relationship for almost 3 years so I’m extremely triggered by this situation and as much as I like him and really wanted him to be it, I don’t know if I can continue this😭 What do I do? Can this still work?😔 This has seriously been the only issue we’ve had in going on 4 months
