Fiance problems cheating possibly

So ever since I started dating my fiance he has had a problem with being on websites and talking to other women. He says that he has stopped but he has not. I know that he is still doing these things and talking to these other girls telling them he wants to give them the d, and saying all these nasty things to them. Every time I confront him he gets so angry, he says he loves me and i am the only one, but if he is saying these things to these other girls i am sure he may try something. We are engaged and I do not want to get married until i know he is done. I have no idea what to do anymore.....I love him so much and need some help...Thank you in advance.

Ok, go on the main forum, find the post that is titled, "I Ca't Stop Crying!" This individual married someone very similar in terms of loyalty in a marriage. He is showing you the every warning flag in the relationship no-no book that you have heard from others most of your dating life. He has a serious problem that will only affect you negatively. I am not saying he cant change, but certainly has to start the changing process by not jumping to anger and getting all defensive. Because that only says that he is hiding something more often than not.
