how do you solve this?

You send them both to hell!! They are both equally wrong for doing what they did. You don't need people like that in your life. I had the same thing happened to me and i cut them both off. With friends like that who needs enemies? They are both losers and you'll be better off with out them. There is no way you can continue where you left off. THIS IS NOT NORMAL!! Good Luck!

Your fiance was seduced. Your friend is not a true friend. Tell your friend to get lost and just fix things up with your fiance. =)

you can say goodbye to both of them-- that would definitely be the first thing anyone would think of doing in that situation- but then, i supposed you know your best friend longer, hence better, than your fiance and it would be easier to give up your relationship with your fiance than with your best friend.. you should actually be thanking her for if not for her you wouldn't have known what kind of person your fiance really is ...they both deserve each other. just cheer up...move on...there's a lot more better persons so don't waste your time and your tears with those cheaters..

Man if i would have been in ur place,i would have kicked my friend's a**. Given up on my fiance too. Reason1-your friend is not YOUR friend...he is,may be was, and may in future keep taking your advantage in the name of friendship!! Reason2-Your fiance does not love you truly, she hooks up with you friends when she's just your fiance, wat if she were ur wife???...it would have been too late then!! So the best thing you can do is give up on both of them and begin a fresh new life. You might get a thought of doing to them wat they did to you...but thats not the right way cause then there would be no difference between you and them. so forget everythin. ALL IS WELL!!

They're both at fault. I would be angry at both of them. My man would never even look at another girl, much less sleep with one. If he truly loves you then you should be the only girl in his life that he would think of in that way, and the simple fact that he would sleep with a friend of yours means he's a jerk. The friend also is not a true friend for doing something like that. I had a friend backstab me once and talk behind my back to a guy we both liked at the time when he showed interest in me over her, even though she was the one who introduced me to him. We were best friends before I found out. I haven't really said anything to her since. So yeah. I would say they're both at fault and tell them both go gtfo.

mistakes make you you realize a lot of things around you. well , i won't call her a friend definitely. i had once had that experience too. i was so mad at my boyfriend. he didn't even thought of my sacrifices for him. and same to that girl. friends don't do that. if i were you ,i'll just ask my man and let him chose who he wanna be with. if your man chooses to be with your friend let them be.. just thinks about the positive side. at least you won't suffer dealing with them anymore. be strong.

Well, it's obvious that your best friend is a traitor. You shouldn't befriends with that kind of person. About your fiance, it's not an excuse that he was seduced. If he let that happened, it means he also like it. It's just a betrayal.

Don't start blaming anybody. Dump the fiance, dump the so-called friend, leave. Move on. Well, it's easy for me to say because I'm single but the thing is, when relationships end because someone's been having too much fun it went out of line, it's easier to move on. It's easier to move on when you're angry. Don't start picking fights because it would only make you stoop as low.

Well, if my "fiance" liked to be seduced and did slept with her, the engagement is off. I don't need a guy who is unfaithful and will just get ahead of himself. If my "fiance" truly loves me, he will definitely try to stay away from my best friend no matter what. OR he will tell me what is going on. As for my so-called "bestfriend", she shouldn't show her face in front of me or else I'll make that face of hers unable to be recognized.

I blame them both. No matter what happens, fiance is fiance. We're getting married for goodness sake. So why should there be room for him to even try and cheat? If that happened to me, I know what to expect, and I'm certainly not expecting for the two of us to get back together again. I respect that person too much, and being an idealist, I would want a relationship without that kind of problem. As for my 'friend' that's the end of that. She's a biatch for even trying to go behind my back in he first place knowing he's my guy.

it is a trial to your fiance. if he was tempted then it only shows how weak he is.. you can blame all of this to your fiance. what about if he will be tempted by other person aside from your friends? it only shows how weak he/she is.. if he/she really loves you, s/he should know what to do when temptations like this come in your relation's way.

I would blame both! Then, break up with my fiance because that mean that he didn't truly love me. I know i would have attached him before i broke up with him! I have been in a relationship and my ex cheated on me with his baby mama! I attached him in a sense of anger! Let's get back on the question" She was never your "true" friend either cause she went behind your back and she knew he was your fiance. So...they are both low for doing that! It's always someone out there who are willing be faithful. True love is faithful, and true love real!

You should broke a relationship with your fiancee because she will never be faithful to you.
