Really need girl advice

A • 🍷👸🏻
Hey ladies, I'm having issues with my current partner and to be honest I don't know what to do. I've been constantly thinking of leaving him, we had a great year and couple months together but I recently found out that he's lied to me about this one girl from the past in 2014. He's also lied to he about couple other things any who for some reason I can't get over the fact that I know he's replaced me for her and I can't seem to move on from it. She told me they've been on and off seeing each other during the time we were seeing but she stopped seeing him because she chose to be with someone else and whoop looks like I'm the replacement for him. He used to draw pictures calls her beautiful and he told me they only hungout once when the girl on the other told me the opposite. He chose her over me because at one point she asked who do you think is better looking and who would you choose over me her or me and of course my boyfriend that wasn't at the time chose her he wanted her to be his girlfriend at the time and not me. I don't know what to believe anymore I know that that's in the past but I can't seem to move on from that😣 I can't believe the person who I thought was my love ended up dressing as the devil. She's currently married and I remember one time we had an argument and I brought it up to him he seemed to care still it's like they were unfinished business.. The worst part of it all he took her out on dates got her stuff but he never seems to do that to me? Doesn't even surprise me when I'm either upset or mad he just apologized, now ladies am I stupid for being this mad and not letting it go without the truth or am I just completely stupid for even feeling like this? i feel like my whole world is collapsing and at this point very lost and don't know what to do... I love him but I don't know if I can pull through much longer😭
