PLEASE READ ALL OF THIS!!!! I NEED HELP BAD!!! I DONT KNOW WHAT TO DO?

Been with fiance for almost 2 yrs. got engaged after only 4 months of dating cuz we were so in love with eachother. kept dating, he lost his job, got depressed, we started to fight a lot and went up to 2 weeks without having . also he started to not like it when i sat real close or kissed him and he doesnt like to show affection unless we are having and he never used to be like that. still, i never thought he would stray. started out him textin my best friend while i was doin his college himework for him sittin right by him. he was tellin her he could make her ***.. i forgave him... couple months later had a g mail chat with a girl he knows sayin the dirtiest stuff that he wanted to do to her... i forgave him.. 1 month later wants to go to his hometown to visit like we did every couple weeks, but for some reason insisted i stayed home this time and come to find out it was cuz he was talkin to a girl that lived there askin her if he could make love to her... i forgave him. he then talked to 3 other girls sayin ual things to them... then couple months later we were fighting so he went to stl for 2 weeks. during this time he had chats online that he paid for and went to several dating websites. now, he found a job there so were in a ldr and he goes to bars a lot and has very high bar tabs... he never says he misses me or even wants me to come see him anymore and just tonight i found e mails on fb from one of the girls i caught him talkin to before... he knows how i feel about this particular girl but he was talkin to her anyways. this morning he asked her when she was gonna take him out for drinks, she said ur the one with the phat job, when r u takin me for drinks. he said i dont wanna message u anymore. gimme ur phone number so i can text u and she e mailed it to him.. so hes been textin her all day most likely... then earlier tonight i got online and looked at our bank account activity and he withdrew 80 bucks probably for the bar, so i didnt look on there and go why were u at the bar last night.. and also went to walgreens and spent about 15 bucks... and i know from experience that the only reason he ever goen in a walgreens was to buy condoms for us and it was always around 15 bucks...... im gonna confront him about it and most likely break up with him... its so hard because despite all these things he can be so nice and supportive and i do love him and he "says" he loves me. what should i do? break up with him? maybe take a break and let us both think things thru? help!! and anyone who read all this thank you so much
