Am I wrong for being disturbed by my husband's past?

Like he did tell me in the beginning of the relationship that he was a horrible person when it came to dating and some how I made him change just ways I am trying to process all of this new information that apparently each month on finding out and to be honest I would have liked finding out the whole lore behind him and honestly now I'm even questioning what the hell did I marry into and is actually making me question whether he's ready to have a kid or not like I knew that he was a fuckboy but I didn't think it was that bad that he would literally cheat on girlfriends and his ex-wife literally makes me question if he's actually going to be loyal in the marriage and to be honest makes me feel like I'm really nothing special I mean I am the second wife so I don't know what to think or what to do

I think I said I do and yes to the ring way too soon I don't know I should have actually found more information about him sooner or I don't know if I made the right move marrying him and I'm scared to find out even more
