Should I forgive capricorn man?

Hi guys,
I'm a leo-vrigo cusp born and I have this capricorn bf for almost a year. We've been in a good realtionship until last couple of months. Cap and virgo is a good match, right? But I have some traits of leo like aggressiveness, sometimes hyper attitude. But that doesn't matter much. But the thing is I had attached to him so much last couple of months and he withdrew. We are sort of like playing games at that time. There're small fights also. Then last 2 weeks, he hit on one of my girlfriend and that is in front of me. This makes me really angry. After that point, I was so over him. Since last week, I don't pick up the ph but he's been trying to reach me. Should he get away with what he did to me this time? or should I reconsider to go into that kind of relationship? Besides that, our personalities are totally different and every opinion towards everything is like north and south pole.
I do need some of you guys suggestion. Please!!!

id tell him straight up WHY that kind of behavior is NOT acceptable. then see what his response is and what he has to say for himself.

"our personalities are totally different and every opinion towards everything is like north and south pole."

I would pay more attention to this. Just my opinion but too much differences can make it too difficult unless you want to put all your energy to argueing and you really enjoy of that.

Thanks CreepyPants and sweet&sour. Yesterday, he called me and this time I don't want to hesitate picking up the ph. since I couldn't hold my anger anymore. So I told him off straightly. He apoligized me so many times. Besides that, he has some family problems. (capricorn loves family, right?) Seems like he can't control everything. He apoligized and told me like he's been stressed with everything that's why he did without intention. But then suddenly he cried. (I can't realize capricorn man was crying). To tell the truth, I feel so sorry when i heard he cried. What do you guys think of his crying?
There's one thing I don't like about him. Last week, I didn't pick up the ph. right? So he talked to me in gtalk. At that time, I also replied him, u know like noramlly we did. But he didn't talk to me very nice. He just say "ya", "that's great", "good for you", just like that. So I pissed off and told him I gotta go. Then i log out. The next day, he deleted me from his list. Then the follwoing day, he invited me in gtalk. But I rejected his invitation. Yesterday, I asked him why he deleted me from his list. THen he said his gtalk was messed up and all of his buddy list was gone. How nonsense!!! I sometimes can't stand this kind of situation. He should at least come up with something that makes sense. Or tell me the truth. Isn't it? Is how the typical capricorn react to the confrontation? Other than that, he's a very reliable person I've ever met. I like his responsibility that I don't have as a leo.
Please leave a comment what you guys think.

Capgirlinlustwithleo, yeah, I do need anger management. You really impressed me. You sound like you know my mind or his mind. That's why I like capricorn. Right now, I feel better and want to make this realtionship work again. I once read that capricorn men don't like to be attached or nagged around him.

So I finally broke up with my cap.. It really hurts. The worst thing is I found out that he cheated on me with my friend before we broke up.. So i confronted him and decided to leave this realtionship.
As soon as I just broke up with him, another cap guy who is my sis's acquaintance asked me out for a date.. I don't know why.. most of the guys approached to me are all capricorn. by the way, I'm Leo virgo cusp and my rising sign is Virgo.
Actually I'm not ready to go see another cap.. cos I really like cap and in the end I feel attached to them emotionally and too dependent on them.. Then the realtionship starts to erupt.
There are a few things I would like to know..
1) Are cap guys emotionally needy? (from my experience, they need attention, compliments all the time.. that really wears me out).
2) Do cap guys remain friends after they broke up? (we decided to stay as friends but it's too recent to decide if it's working or not).
3) Do cap guys forgive? (I've been rude to him when the time we broke up. I can say I hurt him verbally..)
4) Do cap guys manipulate some people to get what they want? (I feel like I've been manipulated)
5) If there's any leo virgo cusp sign, do you have any experience with cappy and how is thing going? I know they really like us but no more than friends.. my cappy told me I'm the best friend he's ever got.. but he doesn't like me no more than friends.
