I've never done this before. So my boyfriend of nearly 2 fully strong years made a mistake on Monday and that was sleeping with this girl. I'm not going to say her name for her privacy and I hate her. They met through his work. I'm really understanding when it comes to him and his chick friends. I let and trust him to talk and meet up with them because I do the same. I became good friends with this girl. Until I found out she considered my boyfriend as more than a friend.

She was always making sure he was okay because of us fighting because of my jealousy and lack of trust toward her. She became really clingy and dependent on him and I hated it. I asked him to stop talking to her, he said he didn't want to because they were friends. Little did he know that she has a serious medical condition. Where it doesn't matter what she wants or who she hurts if she wants something she will do anything to get it. She manipulated him into believing that I was not right for him and she was. She put these stories into his head and he fell for them. She's like poison. I know he didn't do it to hurt me. He never would. I'm in love with him and I always will be. I don't know what to do... :/

Awwwww... the poor baby was manipulated to believe you weren't for him and then convinced into cheating on you with her.

No, I don't think so. He cheated, accept it, don't be in denial about it, he didn't do it to hurt you, he did it because he simply wanted to. Open your eyes, break up with the cheater, and find someone that is going to respect you and your relationship. Also, if you accept this, it will happen again, and who knows how many times it has happened already, this is the time YOU found out.

Get real, time to go no contact for good, respect yourself.

Okay, you know of the one girl. Reading what you wrote - I would delve into his other chick friends and his friendships and I would bet you find he has more than one friend with benefits. If he is unwilling to break off the friendship with her - then you are not of much importance to him.

Seems like the really strong relationship has some weaknesses. Its not good just blaming her though because it take two to tango, and there is no excuse for bad behavior. I mean shagging another female because he feels bad you argued is as sorry as it gets, just as arguing about some female other than you is just as ridicules.

I am sure you both were mean and acted out of impulse, and FEAR, so to not repeat that action you both have to be in control of those intense emotions that lead to impulsive actions, but YOU better pay attention, as it's a big red flag when a partner is so easily mislead by his own feelings. So you both better cool off as you both handled things badly, especially YOU demanding he no longer speak to her, as opposed to say warning him, and letting him see it himself.

I don't know but the results MAY have been different. For sure though for now you both should cool off and see where this goes and maybe talk a bit calmly later to see if what WAS a strong healthy relationship before this girl came into the picture, and if through honest communications if you both are mature enough to forgive and do better, or will your love lead you to blindly patching over the real issues that came between you and destroyed that trust, and confidence in each other.

Maybe your love was blind, and you had issues you overlooked until this happened and you must face facts! Not to defend him at all, just saying use your head and NOT just your heart to figure what's the best thing to do for you both, and a question, a few actually, how old are you both, and how did you find out he had sex with this female?

How did YOU know she would be trying to draw him away from you to her?? Please be specific with details and a time line. I ask because according to what you wrote, you did worry about his other female friends, just her, and I want to know why exactly of all his friends he turned to her, and ended up cheating.

But hell NO! I wouldn't advise taking a cheater back, and it doesn't matter how much love you have! To many things have to happen before a broken trust is made whole again.
