Why are you not together now? More info would be helpful.

I agree. You aren't really giving us anything to go off.

We need some details.

What kind of relationship did you have?

Why did you break up?

Well we lost a child in 2000, we've been living together for about 9-10 years. I left him three times, the third time he got someone pregnant and when we got back together he didn't say anything. This time he called it off cause he said he didn't want to reach 40 and I'm looking back with regret or he is.
I came home from work early in September and there was a girl in the house. He said he was giving her a lift and she wanted to use the bathroom. It seemed like nothing happened cause when I called about 10 minutes earlier he was on the road, I heard it in the background. And I didn't find any evidence. But after about 2 weeks, I asked if I should wait for him after work and he said he's still in town and he's coming up late so I should go ahead.
I decided to pass by the apartment and he was parked now exiting the vehicle and so was she, the same girl I saw in the apartment.
He swore they were just friends and she have a boyfriend but things went a little too far with them. He said they never had sex or been intimate.
I emailed the girl and asked what was going on and she replied that it's none of my business or my concern.
My ex said the reason we're not together has nothing to do with her...

Sorry for your loss, but I have to ask if you have any children together? Frankly, whatever his issues, you have clearly spent enough time, and energy on this guy, and should leave him, and his life alone, and pursue your own happiness without him. I think you are long overdue.

How many times does this guy need to cheat on you for you to get the message? I don't mean to be harsh, but come on, stop letting someone walk all over you! Don't you think its time to move on and find a real man that will actually comprehend the meaning of honesty or just simply what is means to have a relationship. I mean do you really think this type of man is going to change? How many more years of your life are you going to WASTE wishing and hoping for him to REALLY LOVE you and stop cheating on you. I think 11years is plenty of time to throw away on a loser!!
