I ‘26F’ am with my bf ‘27M’ since past 7 years. We had a good relationship and i or him never doubted on each other. But idk what happened and one sudden day i started scrolling his WhatsApp and i saw that he had some physical relation with his ex best friend before me. That was the time when he was trying on me. Then almost around oct (7years back) we were together but still he went to a trip in dec and made out with her. Although it was before me but he never told it to me.
Then when i confronted abt all this to him he told me that when we broke up for 2 months 3 years back he then made out with his office colleague. Then 2 years back he went on a boys trip there he had sex 2 times. And it made him guilty a lot. But a year back he sexted with his other friend but it was only twice.
He told me it had all made him very guilty and he is accountable and was crying and wanted to tell me all this from long back ago. And said it wont be repeated.
What should i do now? I really love him.
