Summer Fling turned into nightmare

[bluthre]

my husband is 28 and I'm 27, we have one son (6)
together 10 married 5
never talked bad about my husband but did tell the guy I was single and wasn't involved with anyone other than dating. I did that because I didn't feel the other guy needed the truth I never expected him to be anything other than a fling and there for some emotional attention.
