Background:
My DH was first married to another woman. He loved his first DW dearly. However, the whole relationship was a nightmare. She cheated on him multiple times, in fact she is now married to last man she cheated on him with. She was also violent and abused my DH physically, to the extent that he would wake up the day after one of those episodes covered in bruises. When she got angry, or could not get her way, she would scream all insults and swearwords under the sun at him, and hit him with her hands and any object she could find. On one occasion he held her hands to prevent her from hitting him. She threatened to report HIM to the police for abuse if he did not let her go... just to go on hitting him.
My DH put up with this for years because he loved her, and because he would never raise his hand to a woman.
After many years of suffering, she cheated on him one last time with a co-worker and he made the painful decision to leave her. She is now married to this guy and has had a child with him.
I have only learned the full story (and I am sure there are still bits he has not told me) after a long time of small bits of information he was able to give me one at a time. This part of his life is very painful to him. His family know about the cheating, but I believe he has never told them about the abuse.
My DH and I met after he left his Ex-DW. He is the most gentle, sweet man. We have been together for 5 years and I love him dearly. We got married last year. Every time I think of him suffering the kind of abuse he suffered by someone he loved so much I seethe inside and my heart breaks for him. Fortunately, his Ex-DW and her current DH have emigrated to another country, so they are now too far away to cause him any more harm. Or that is what I believed.
Now let's move to the story...
I have a FB account that I only use for my studies, I must have about 10 "friends" on it which are mostly other students. My DH has no FB account himself. I have my SIL (my DH's sister) as a friend just so we can see our nephews' photos, that she posts occasionally. She does not use the account very often either.
Some days ago I had a look at her FB page to see if there were any new photos. And I got the shock of my life when, on the random selection of 9 "friends" that the home page displays, I saw my DH's ex-DW there, smiling at me with her DH.
I know it's none of my business who my SIL chooses to befriend on FB. I do not even know for how long she has had her as a FB friend, as I have never looked into her list of friends and I just saw her because she happened to appear on the random selection. There may be a legitimate reason why she is there.
But I am enraged. Why would anyone befriend the person who cheated repeatedly on her brother, and that is now married to the last guy she cheated on him with? Even more, now I feel "naked", that through my SIL's account she cabn see my account. i don't post any photos of me or my DH, but my SIL may do at some point. And I really don't want this woman to have any kind of information or access to our lives.
AIBU to feel like this? What the hell do I do? Do I just keep my mouth shut and try to ignore it? Would you say something to my SIL? I really am at a loss :(. But I am really hurt.
