About a year ago, my family and I went to visit my SIL and her family. They were rather cold and distant towards us. In fact, we felt like we were bothering them by visiting. Something we found odd since they'd been begging for us to come visit. I later found out my MIL had told them some nasty lies about us and they were in fact angry. My MIL is notorious for misreading situations and people, seeing things as problems that aren't, and quite frankly, she's been caught being a bit devious by stirring up trouble just because she's jealous. It's a known fact between me and my SIL to take whatever my MIL says with a "grain of salt". So I was very saddened when I received an angry message from my SIL accusing me of gossip and prejudice. She fired one accusation at me after another, then insulted me by calling me pathetic and childish. I offered up a defense for myself trying to explain the truth of the matter and expose all the lies told to her by my MIL, but she would not hear of it. Blocked me on social media and has refused to speak to me for over a year. Here's the thing....my SIL had a choice when she heard the lies. She should have known it was all garbage, but even if she did not, she chose NOT to call me and simply ask me about it. She accepted the lies as truth and threw me under the bus. Apparently I mean so little to her that she did not have the courtesy to extend to me by asking me about the lies first and opening the chance for discussion. I don't like people like this. they are back stabbers and can never be trusted. Curiously, my husband and I recently received an invitation in the mail from my SIL. She and her husband are having another wedding for themselves to celebrate their 30th wedding anniversary, complete with a registry asking for gifts and money (which I think is BEYOND TACKY). My husband is going, but I'm not. No way will I sit there and support them as family when they've treated me like dirt. Am I right to take this stand?
