So this weekend I am going on a precovid planned trip to OBX with my in laws. I have some unresolved issues with three of the women going. My sister in law and two of my husbands cousins fiances. The problems with my sister in law started back when i first started started dating my husband 8 years ago. She used to criticize my looks and weight. Tried to fight me on a family cruise because of a difference in opinion on whether we should discuss sex at the dinner table. This had her removed from my bridal party. She then refused to attend our wedding stating she couldn't attend a union she didn't support. I tried to let her know there were no hard feelings and we wanted her apart of our lives and she said I had been too disrespectful to accept. I have never been disrespectful to this girl. Then I got pregnant with my son and she did a complete 180 after no where. We never diacussed how crappy of a person she was to me. She just wanted to be apart of my childs life. She later did a few shady comments to family member about me and in front of me but later took it back because she realized i had the power not to let her see my son. So i am pregnant again and that best friend mentality is back. The two fiances are have become the best of friends but we all got with our SO in the same summer of 2011. They have always had an issue with me but they won't tell me what the problem is. They just are mean and snaky to me 1 day, saying no one needs me or wants me around and then nice and asking me about my pregnancy the next. We had an entire argument on a group chat because they thought i was being shady with a comment about husbands and talking to them before making plans for them and i wasn't at all. I have been uncomfortable around them ever since. Should i just let it go? I feel like I never got closure and like i have to be fake around them.
