FML!!!

I literally puked for an hour this morning and not from the booze, What the ** happened last night, I went out for a few drinks and I woke up in bed with my best friend and her husband, How did this happen, this is not me, What am I going to tell my husband.
I remember leaving the bar, then I remember sitting on the couch with her then all of a sudden I wake up and he has his arms around me from behind, Squeezing my ** and his ** in me, I didn't even clue in right away until I felt something out of place, then I opened my eyes and she is sucking on my **, Both of us naked, Her arms and legs around me and sucking my **, What the actual **.
I was so wasted I did it, I kept going and let him ** me, Its like I couldn't get back to reality, I came laying on my side while she rubbed me and her husband had his ** in my you know what, Every time I think about feeling him come inside me makes me gag, I have never been with anyone since I got married other than my husband.
I couldn't figure out what was going on and I couldn't stop, I just kept doing stuff, it wasn't until this afternoon that something she said finally clued in, "I never thought your tongue would feel so good in me", Oh my god, please, I cant even leave my bedroom, I cant look anyone in the eye.
I called her and asked what happened and she said it was my idea, She said we started making out on the couch and I, Me, I was the one who said "lets go to bed together", No, there is no way, the things she says we did to each other I would never do, I would never give another man head, I would never go down on a girl, Never, Never, Never.
This cant be real, I walked two blocks home at 4:00 in the morning and don't remember it, I walked home in shoes a skirt and a t-shirt that is not mine, Thank god my husband didn't wake up and wouldn't have any reason to open the laundry hamper let alone look in it in the morning, Thank god he is gone to work while I figure out what I am going to do, I have to return his shirt and get my bra and ** back.
I don't understand how this happened or even what happened, I cant stop crying or gagging, I have nothing left to puke up, Everytime I remember part of it I start crying again, What am I going to do.
