šŸšÆSide hoes and insecurities! Need advice ladies *updated

OK so something very weird just happened and I want to know what you guys think and what I should do. So I have been dating this guy for almost a year but there was a time when we were split up for about two months. During that time he went and hooked up with girls and one of the girls was this chick who I was ALWAYS suspicious about because he followed her on Instagram etc. When we first started dating I even heard him and his roommates talking about this ā€œsexy bitch at the gym.ā€ Mind you, this is the kind of guy who will take my phone and look at who follows me and who I follow and will say something if he doesnā€™t know the person. Heā€™s a bit controlling and so am Iļø.. within those two months of being without him I realized that I never want to leave him again because I do believe that he is the one and all that.

He did the decent thing and confessed everything that he did with her which was only a blowjob but still I feel like he is not telling me the full story of what happened with them.

For some really weird reason I cannot get this bitch out of my head. Like it keeps me up at night. I think about it when I am sleeping next to him... And I even brought it up to him this morning questioning him. I hate to become such a naggy girlfriend but why am I so insecure about this?

Today I decided to go to the gym for the first time in two weeks because I want to get back into it for myself and I kid you not, as I am pulling up to the gym, this girl is leaving the gym and WALKS RIGHT IN FRONT OF MY CAR. THE SAME FUCKING FEMALE THE Iļø WAS ALWAYS WORRIED ABOUT. And I see everything I see her body type and she made me feel so less of myself. She had such a big butt and thick thighs which is something that Iā€™m sooo self-conscious of right now because I lost a ton of weight due to the two months of being without my boyfriend and being depressed. That about did it for me. My self-esteem is so low right now. Iļø donā€™t look like that. Iļø am a tiny blonde with short hair. This bitch is thick and has long as gorgeous hairrrrr. Like Iļø donā€™t get whyyyy.

I told my boyfriend what happened and he tried to do his best to make me feel better but it just isnā€™t doing it and Iā€™m just upset. To think that he touched a girl like that I canā€™t help but think why? Why is he with someone like me when he can obviously get girls like that.. Iļø feel like shit about my body because Iļø used to be like that but Iā€™m not anymore. Iļø dropped about 20 lbs in weight and canā€™t seem to build it up. Iļø feel so shitty rn. Any advice on how to handle this and maybe become not insecure about other hoes when he CAME BACK to me.

Thank you for taking the time to readā¤ļøā¤ļø

UPDATE******

Okay you guys so Iļø literally just found out that he STILL follows her in social media and Iā€™m specially talking about Instagram. Iļø do not use this so when Iļø saw it Iļø was stunnedšŸ˜­šŸ˜£ Iļø even confronted him and he says this

ā€œMe following her does not change a thing what donā€™t you get. It should not matter at allā€

šŸ¤ØšŸ¤ØšŸ˜ šŸ¤¬šŸ˜” Iā€™m fucking pissed.
