Why did he do this to me??

あなた can be the bigger person and forgive him, but I wouldn't take him back または anything. He's a player. あなた now know this to be true. If あなた take him back and he plays あなた again, then it's your fault for trusting him a 秒 time.

Cheaters often don't change their ways, and the fact that he's denying that he is a player shows that he hasn't learned anything.

As I 発言しました before, あなた can forgive him; but if あなた take him back, don't be surprised if あなた get hurt again.

As the famous saying says...

"Fool me once, shame on you. Fool me twice, shame on me."

Tell him to leave あなた alone and to get a life. Having multiple girlfriends at one time is something a douche would do. But I guess あなた could forgive him but don't go dating him または anything.

....by the way, what's with all the 愛 質問 today, this is like the fourth one I've seen -.-

Because あなた don't lift.

tell the dumdums 3 other girlfriends
so they can kill him

あなた should forgive him just because it does not help to hold a grudge. あなた will also be the better person. But あなた should not get back together with him cheaters do not change there ways normally.

Don't complain about your problems on here just because people are idiots in life.

Users on this club hate seeing 質問 like this about a girl sobbing over a guy who cheats on them.
There a total nuisance and あなた should figure out how to deal with the problem other than having internet フレンズ who can't help あなた do shit but give advice.

Forgive but don't forget, but don't be in a relationship with him.
Cool men don't cheat on their partners.

Be an elephant...maybe forgive, but never forget and never take him back.

Ugh. He did it to あなた because he's a jerk. -.- And he must not really like または care about あなた so much if he would deceive あなた about something like that. I'm sorry.
If he is sorry, I'll advise あなた to forgive him. But maybe あなた should watch him もっと見る closely 次 time... and make sure that he's sorry.
I don't trust that guy... >.>

I Would Dump The Boy !!
And the other 3 girls know that they are not his only girlfriend ??? If no, maybe u can say it to them ???

He is just super imature, and if he loose all his girlfriends, maybe he would change ???

I would say to not to, 3 other girlfriends?!?! I've only heard of 2 at once....... He is a big time player and if あなた forgive him, thats exactly what he wants, dont and when he looses his girls for a while, he will start to understand how much あなた were hurt.

あなた go girlfriend!!!!!*starts tearing up*
