I have been missing my boyfriend because I went to Maui with his friends wives and wanted to surprise him... I text him the morning of and told him I couldn't wait to see him. Instead I went over to surprise him with gifts and a hug... to find woman's boots and purse near the kitchen table. I called out his name I guess in time enough for him to lock the door. I broke it down as my daughter was in his kids bedroom (they weren't home thank god) and I saw her scared as hell on our bed under my covers on my pillow... I screamed why and smashed her things and then he came out of the room and grabbed me to remove me from his house... I am mortified... crushed... we were about to move in together then he got cold feet... I accepted that and moved on in the relationship... he tells me he hates hurting me and loves me but won't tell me how long and who is she... its been 4 days of not eating, sleeping and the most intense pain I have ever felt... he helped me through my past relationships because we were bestfriends. I love his children. This wasn't suppose to happen. Someone wake me up please from this nitemare.

What a harsh dose of reality, but don't go back. I am speechless but hope in time you will take care of yourself and put this behind you.

I wish there were magic words to say, but there are none, as I can only pray for you to heal, and be better soon.

Hug your daughter for me.

Wow I really can't think of anything worse than that, like Tal I am speechless. Just be the classier of the two and keep your head high, even though I know it's hard. With time you will get through this, you are better than he will ever be

I'm sorry,how truly earthshattering this must be for you.

You must still be in shock,have you got family and friends around to support you?

I can imagine your shock, and emotional trauma.
It can be the worst think people should tolerate.

The good news is the relationship is clearly OVER.
The relationship you had was not what you thought to be.
He is not love of your life, but malicious cheater.
You said “we were about to move in together then he got cold feet”, and it is lie. IT WAS NOT COLD FEET. HE DID NOT WANT TO GIVE UP HIS FREEDOM TO SLEEP AROUND OTHER GIRLS while he is sleeping with you!
While you were in trip, you constantly talking to you to comfort you, but he jumped on the opportunity and BROUGHT A GIRL IN YOUR BED and had sex right there!
HE IS NOT A BEST FRIEND. Best friend does not lie to his friends.
HE IS NOT A GOOD PERSON. Good person has good moral, wait for lover, but not lie, and sneak around. He is wolf under the ship skin.
I am glad you found out his true color now, not years later you wasted you life for this monster.

Please thank god, who made your eye opened for you with purpose, accept it, and try to heal from your trauma. I guess you are very confused by shock, and hard to swift your love to hate feeling, but it will work out fine eventually. Please do not waste even a minute to think about the useless monster.
I suggest you see a counselor, talk out all your anger to release for your well being. I guess it is very good idea you come to here vent as much as possible. Otherwise, you will suffer for the shock and pain for long time, and it will change your future relationship.
Your kid should be in shock as well, and need some treatment as well.
