So long story made short we been together 15 years we both only been with each other we got married 5 years ago and we were trying for a baby since we got married finally got pregnant 2 years ago but I lost it it about destroyed our relationship we no longer are interment we don't talk or spend time with each other. I have heard he has cheated on me twice but never confronted him because in all honesty I don't care that much. So last week he and his best friend went out drinking which happens very often he get to the point where he passes out and sleeps in the spare room so l was down stairs and his mate was on the sofa. I come down and he said are you okay and I lost it was crying and told him how unhappy I am. This was going on for over an hour and he then cuddled me l have no attraction to him. Basically we ended up kissing and it got me going so I touched him we ended up having sex we dident go all the way he dident cum. Am I the arsehole? I slept with my husband best friend
