This sounds very familiar. W went to Mexico with her daughter (18 Yr.), sister and mother Mem. Day weekend. I knew something was up almost immediately. I start snooping around and sure enough she had a "friend" that she met at the resort and had sex with, referenced it pretty explicitly in emails. The worst part is last weekend (June 1) was our 5th Anniv. during the time she's with me, she's emailing him from her cell ph. THEN to top it off, she sends him pics of her that I TOOK on our weekend! I find out and she freaks that I was "snooping". I don't know if there's anything left to salvage. Over the 5 years I've realized that she has many issues she needs to deal with, RE: relationships with her parents (both D & A abusers) and just her past, she appears to me to be bi-polar but I'm not an expert. She refuses to go to counseling with me, saying it's my problem not hers and she still denies having had a physical relationship with this guy in spite of the email evidence. I'm not sure what to do but I'm looking into D.
