<human>: Can you give me a shortened version of the text?

Well, Reddit. Here's my sad little story.. I've been in a relationship for over a year, and hell, it's been one messy year. I don't want to go into too much detail because I've actually been borderline stalked in the past (if something vital seems to be missing, tell me?).. 

Me and my SO are both 20-something young adults. When we met, we immediately hit off and thus starts our story. We spent togethet probably the best summer ever, but then things go wrong. Enter the manipulative ex-gf, a girl who gets between us a couple of times.. A lot of other shit happened too and being passonate and well, maybe a little immature too, we break up & make up a couple of times, the last time being about four months ago.

We got quickly back together, and my bf seemed to change; he's actually made an effort to keep other people out of our relationship, and he's also been sweet and caring.

Problem is, I found out that during our quick break-ups he made out with a couple of other girls in a drunken haze and later on lied to me about it, because apparently he was too ashamed to tell me. As far as I knew til yesterday was that he kissed his ex last autumn, but oh no.. The number is actually three other girls he kissed and tossed away. I found out because I knew he had erm, asked at least one of these girls' number when we had broken up and he was mad at me, so I confronted him about it.

Things have been going so well lately, but oh man.. Truth be told, I don't think I would've gotten back together with him had I known he actually kissed THREE other girls, and most of these episodes even rooting as far as us breaking up because of his ex. These were dealt with in winter, but obviously he lied to me. He cried last night when he thought I was going to leave him. Things have been better, almost perfect, after we left all that shit behind but now.. How am I supposed to deal with this new info? Obviously he was ashamed and still is, but lying straight to my face? That's bad..
<bot>: break up & make up with bf, things get better over time but it turns out that during break-ups bf kissed three other girls and straight out lied about it firsthand
