New girl

Well my bf & I had broken up but while we dated we both lost our virginity to each other and tried many things. Well we got back together any who during that time he had a friend with benefits and they obviously fucked well now he told me all the things he tried with her like for example he fucked her raw and when we were together I would want to fuck raw but he never did because he was “scared” and honestly that got me mad af because how are you going to fuck some other bitch that wasn’t even your girlfriend raw and not me like wtf. Well he also told me they had tried anal sex and he told me back then when we dated that he would like to try it but I never did and it also bothered me that he had tried it with her. I don’t know if I’m being childish but that just gets me sooo mad because he was my 1st for EVERYTHING and I wanted to be his 1st for everything too but since we broke up he fucked someone else and tried new things that just has mee fucked up.

Like how do I get over that stupid thing??? I don’t wanna be mad or nothing that he tried new things with that other girl because I feel like it’s really stupid but I don’t know how, it’s just really hard for me😩
