My husbands ex/step kids mom and I have a rocky relationship. We’ve know each other about 2 1/2 years now and I’ve been married to my husband for a year and 7 months. When we first started dating she reached out to me and was nice to my face, but would complain ALL the time to my husband about me. He stood up for me and ignored her mostly. I was nasty to her after a few months of this and then I apologized and asked to start over for the kids sake. She denied this and was nasty again. A month later when we got engaged she offered to help with the wedding. We ended up getting married in Vegas since it was both our 2nd wedding. She got pissed. Then a few months later she was constantly asking for my help with the kids, but would STILL be rude to me all the time. I never fought with her, just ignored it. Fast forward to now, we’ve had custody of the kids since last April, she still acts like I’m clueless on being a mom. Over Christmas she was sooo nice and I was neutral with her. At this point I have NO desire to be her friend or contact her, I let my husband do it all. Before Christmas she sent me LONG messages basically acting like I have no idea how to be a mom and was super passive aggressive, but at the end of the message she offered to do a gender reveal for me?? I told her no thanks. I thought it was so weird. This baby has nothing to do with her and I don’t want her involved. I was really friendly but just said we had already done one. Couple weeks later she told my husband she was “done speaking to me” lol. Fine by me!! I’m just so curious why she goes out of her way to be rude and also nice to me. It’s exhausting and never ending.
