so my bf(21) of one year and a half told me today that had an affair with a 40 year old woman before he met me (i'm am 21)...he told me he did it bacause of the milf fantasy... but now that he is older he understands that he could have done without it and it was nothing special at all. now i can't keep it out of my mind. he has done some other things that freak me out like sleeping with his bfs first gf (before he met me too). i know that hes changed since then. also i know ive helped him a lot to be who he is today. but i keep thinking about his past and it makes me feel inadequate and question myself. i didnt have serious experiences before him although he has been experienced enough (long relationships etc). i know that he's felt and done things that i do or feel for the first time so are they as special to him as they are for me? i know what i am good at and that he admires me, he even gets jealous of me sometimes because i achieve every goal i set. but then i am thinking that he did this or that and i imagine pics...i cant stand it. of course i play it cool and don't react. but is this normal?
