Do I rat out my brother in law who is possibly cheating on my sister?

Infidelity/Cheating
#1

I have a page on facebook and so does my brother in law who is married to my oldest sister, she does not have a facebook page.

Over the past month or so I have watched my BIL banter back and forth with a woman from another state. It went from friendly, to flirtatious, to bordering on inappropriate. He has a motorcycle and was hinting on his facebook page that he wants to take a road trip to her state!

For the most part my sister and BIL are not even living together during the week because my sister babysits her grand daughter and stays at her daughters house. Plus my BIL has a history of severe depression and alcoholism. So what do I do? This will really upset my sister who is a wonderful person.

Honestly- I had to think long and hard about this one. I put myself in your shoes and came to the conclusion that if it were my sister I would go to her. I am assuming you have a good relationship with her? If you don’t have a good relationship I would just let things go. My sister and I are tight - so are my brothers and I . We all have pitched in when the other needs us. Blood is thicker than water. I would tell my sister or brothers if I had some thing other than I think to tell them.

I don’t do facebook, so I don’t know, but…if you can see what her husband is doing, can’t his wife? If so, then she knows already.If I were you, I would say something like, I saw some really odd things on his facebook. Have you checked it out? and let her see what’s there for herself.

My dad caught the stbx with the ow and didn’t tell me. Imagine how I feel now? The stbx got up one morning and left. I had no idea it was coming. I could have prepared myself emotionally and financially if I had known. I don’t speak to my father any more. I consider his failure to tell me to be betrayal.Tell your sister. Tell her exactly what you said here. Maybe let her read this page. You don’t have proof, but if he’s saying inappropriate things even if he hasn’t acted, she should know. You don’t know if he’s having an affair, but she should at least know what you know so she can hire a pi or do what she needs to do to take care of herself.
