Ughhh

Hey guys ... so when me and my boyfriend started dating me him and a friend were playing never have I ever. Well he fessed up to sleeping with a 40 or older year old mother of a girl on his cheer team. He told me it was years ago I still felt disgusted but at least I tried to water it down with him saying it was a year or 2 ago. Well a couple months into the relationship I somehow came across his instag ram and came a across a photo on the trip where it happened but the date was just a couple months before we met so he lied. I confronted him about it and he said he was worried I would leave him so he told a white lie But I was pissed because I don't know how to feel about it like first of all wtf that's an old lady twice your age or older and that's your cheer mates mom like wtf what if someone banged your mom? Just totally against my morals but I kept trying to be the "bigger" person and say it's the past OK well guys.. it seriously ate Away at me for the longest of time like I've been one to stay away from guys behavior I didn't approve of... he also almost got a girl he met off tinder pregnant, and slept with a underage girl like he's stupid like legit sometimes like he's so gullible she said she was on birth control but pulled the I'm pregnant card. Then the other girl confessed she had a bf and told everyone they slept together so all the gymnastics peeps judged him. Anyways at this point we were deep in the relationship but always in the back of my mind I'm like wtf. . . But there's worse guys right like he's never cheated on me treats me good now he was horrible at first .... but I blame that in his parents divorce but still like wtf . . . Well now today again I've been thinking of that stupid 40+ yr old and he said she somehow talked him into it and he felt super lonely and desperate for any attention but like daaaamb that's soooo low he said she looked old even in her face so he to me just sounds like a loser but like I said I'm finding all this out like almost 2 yrs deep in the relationship I want to move on he treats me good now but I'm still pissed that he was so stupid like wtffff but he cries about the past so I know he genuinely feels bad and wasn't in the best place but it's just my personality that's like ehhhhhhhh but trust me I'm doing my best I want a future I just hate remembering this stuff like to be honest it sounds like she was preying on him and took advantage and that pisses me off too she's divorced druggie and alcoholic so like idk how he was stupid enough to even associate with her but I also blame his parents they were all on that cheer trip and he somehow ended up alone with that botch she bought him drinks and suggested they meet with his friends in her room well guess what they didn't come but she just went at him. Then somehow got him to go to her house sometime after they returned from the trip like wtf man she hard core preyed and took advantage of his ass
