I luv my husband more than anything. I just had a friend come over while my SO was out of town and one thing lead to another and I slept with my him. I feel terrible and don't know if I should ever tell my husband because it would ruin our relationship and it would devastate him. He's the perfect husband and I'm an idiot. Should I tell him and if so, how? Or should I keep it to myself so we can remain happy? He trusts me! This is the first time and I could never do it again cause I feel so bad for it.
