I'm in my late 30s, male, and had a messy breakup with a long term girlfriend 1 year ago.
My sister in sees her in work about once a month. I generally get along well with my sister in law. However a month after we broke up the sis in law tells me the ex has a new boyfriend. Then she tells me about 3 months after the breakup the ex is engaged. Then 6 mts ago tells me the ex had a lovely wedding. A week ago she told me she was pregnant. I end up saying nothing really and I'm sure looking a bit awkward.
I don't want to know anything about my ex's life! Why does she keep bringing her up? It still brings back unpleasant memories, and she knew the ex did a lot of nasty things, like dumping over the phone, stealing money, cheating etc.
