Men that cheat on their wives often use the line, “I hate my wife, so it’s OK that we’re having sex.” That’s how you got drawn in. Because he claims to hate his wife, it appears that you are “saving him.” You’re not saving him, he’s using you and he’s cheating on his wife.
If this man really hated his wife and really loved you, he would get a divorce. Divorce may be inconvenient, but in this country (I’m guessing you are in the U.S.) it’s legal. I’m sure he’s got all kinds of excuses for why he can’t get a divorce. I’m sure the main reason is because he doesn’t want to get a divorce.
You aren’t helping matters at all by continuing with this charade. Even though you might be a perfectly nice person in general, right now you are the definition of a homewrecker. It doesn’t matter how much this man claims to hate his wife. Maybe he hates her, maybe he doesn’t, but you still chose to help him cheat. Even if you fell in love with him, you still had the choice to stay out of their relationship.
You should have a serious talk with this fellow and let him know that if he wants to be with you, then he needs to start the divorce proceedings right now. But in the meantime, you should cool it completely with him, otherwise you are still just having an affair and that’s not fair to his wife or his children. Let them sort out their relationship first, then after he’s divorced, if he still wants to be with you, he can.
But you have to realize that if he cheated on his wife, he’s likely to cheat on you too. He apparently thinks it’s perfectly fine to cheat, because he’s doing it.
You are right that you can’t help who you fall in love with, but if you put yourself in a compromising position with a married man, you are much more likely to fall in love with him, than if you simply didn’t allow yourself to get into that situation in the first place. You didn’t fall in love with him from afar, you fell in love because you jumped right into the situation. Things don’t just happen, we let them happen.
I’m curious to know what reasons he gave you for not being able to get a divorce? And why on earth would you or he expect that you would “die” if you weren’t in this relationship. I hope you don’t mean that literally. I think now would be a very good time for you to step out of this relationship and get into some therapy to figure out why you’ve allowed yourself to get mixed up in something like this and get some good advice on how to avoid these kinds of situations in the future.
And just for a little perspective I’ll let you know what happened to a former friend of mine. She was in a very similar situation to yours. A couple that my friend knew were having marital problems, the husband came to my friend for consolation. He told her that his wife was really awful and they hadn’t been on the same page for quite awhile, even though they had a 2 year old son. My friend felt very flattered that this man came to her for consolation and immediately they became intimate. My friend repeatedly told me how awful the wife was and that if she didn’t hook up with this guy right now, that she was bound to lose him forever. So she started dating him (without the knoweledge of his wife) and she fell madly in love with him. But he was still living with his wife and child. My friend started to resent the fact that he had to spend time with his son. I tried to explain to her that his son had to be his first priority and she would never be his first priority. She started to push him to get a divorce. He didn’t want to get a divorce at that point, because his wife had no ideas that he was even having an affair. Because they all had mutual friends, it became evident that my friend and this man were having an affair, and his wife found out pretty quickly. It was ugly. By that time, the man told my friend that she needed to make a decision right away as to whether she was going to stay with him (and continue the affair) and wait indefinitely for him to get a divorce. She chose to continue the affair, but she became very resentful because he was dragging his feet with the divorce and continued to spend most of his free time with his son. The man ended up dumping her, then he got together with another woman (who was also a mutual friend), got his divorce, and then married the second woman.
Part of the reason that this friend is a former friend is because of this particular situation. I thought it was really awful of her to get involved with a married man, no matter how much the man may have claimed to dislike his wife. Those are two separate issues. My former friend became very desperate, after having been dumped, and proceeded to date about 30 different men over a period of 3 or 4 years. She eventually married a man who I thought was a total douche-bag. Don’t let any of this crap happen to you.
