Trust..

Ive been taken as a fool in previous relationships, I have had a lot of issues with men growing up due to being taken advantage of from a younger age and recently I've been really struggling with trusting men and most people in general. My boyfriend was under extreme stress recently and he told me he had been fooling around with girls, not in person but over messages he has told me he really feels guilty and hates himself for doing it and im really unsure in what to do. We have had alot of issues in the past and we have dealt with them together.. i dont wanna end things with his as he was my first and i did loose my virginity to him, I honestly really do love him. Please someone helppp, im completely lostt 😩am i being stupid or whatt😅
