Don't forget about karma too, it has a way of making its way back around. I try to keep this in mind with whatever I do and it always helps make some positive choices.
True friends don't do those kind of stuff,you knew from the begining your friend liked him and you know she's going be hurt when she finds out.That is what dirty nasty bastards do,personally i don't think that relationship will last.
lol just for fun I have to add that a lot of the times I would find out that the guy would "brag" to his guy friends about getting two friends to like him at the same time. That alone, always made me think twice :D Never know what someone's intentions are. So keep your best interest at heart.
Rats! Your friend is going to have an ego bruising in two ways. First, the guy like you and not her . . . that always feels really terrible. Also makes it quite awkward. Second, you hooked up with him and have been doing so ever since behind her back rather than being up front and doing things the right way. She might call you sneaky now even though you were doing it because you don't want to make her feel bad.
Okay----------- never has there been a guy worth making a really good friend feel like c rap over in my life. Guys come and go. Loyalty rules!! I know every one of my girlfriends that were disloyal to me . . . from WAY back. I remember who they are and I didn't stay friends with them.
So, what can you do now? You like the guy and he likes you and I'm guessing it is worth it to you to keep seeing him. So---------- go visit your friend. Throw yourself on the sword and tell her what happened. Tell her how sorry you are. Tell her you wish you didn't like him so you could just dump him. But you do like him. And then see what happens. She may take her pride and eat it and say "okay" and move on (while NOT introducing you to a guy she likes again . . . sorry but that is the truth. She'll be hurt.) OR she will get mad. If mad, the friendship will either repair over time or be over. Time will tell. I'd promise that you'll never lie to her again. I think that I'd do nice nice things for her right now. And I think that I'd do my very best to make her feel comfortable if she ever has to be with you two again. Rejection for a friend really hurts. She needs some TLC.
Anyway, like I said---------- guys weren't worth that kind of drama for me when I was back in the dating days. good luck
I never had a love triangle work out or result in a long term relationship. Usually the friendship gets crushed and the guy does the same thing to you down the road with someone else. So I would ask you this, how would you react if your friend was in the same situation?
Some of this depends on how old you are. (Good girlfriends are worth their weight in gold at, say, age 45, and a woman would take seriously that it might hurt her friend, to the point of delaying seeing the guy until a little time has passed. And, at 45, a guy might wait, if a woman he finds attractive asks him to for that reason. It's considerate, and prevents awkwardness.)
But doing something at a party because you were "pretty drunk," and trying to justify hurting your friend's feelings because would not like to miss a really great guy, makes you sound a lot younger. :) I'm not saying to forgo the guy, but I do think you have to consider that seeing him is going to make your friend feel like you stabbed her in the back, so at least be ready for that reaction.
If you and the guy are enjoying each other's company and communicating well, maybe you could tell him about the quandary this puts you in, (i.e., that you're in a spot because your friend likes him too). You could then ask if he would mind waiting for a bit before seeing much of each other. If you don't want to try this because you think he'd just walk away, (and if that idea makes you nervous -- I'd let him walk away if he is that inconstant, but that's me), then you do need to talk to your girlfriend. She deserves a chance to be mad at you, for grabbing the guy she thought you understood she was interested in for herself, and also because she'll probably be hurt, and mad at your luck where she struck out. At least she can yell at you and feel a little better.
What if you pursue it with this guy and hurt your friend's feelings and it winds up going nowhere?
