Sorry Broken. It's a shame his behavior is taking away your pregnancy joy. It's not fair. Some people seem to always pick the worst times to swoop in and destroy happiness.
I'm also struggling with my stepmom. My dad passed away in January, so she's been having a hard time, obviously. Growing up with her was not easy; she was one of those types that needed every ounce of attention for herself and would get jealous when dad would spend time with me. She didn't like that my dad had other interests(like hunting and fishing) and gave him an extremely hard time if he went. She was verbally abusive to him at times. Honestly she ruined the relationship between my dad and I. She wanted attention from me too, and I hated her so much that I couldn't bring myself to give her any and found myself avoiding her on a daily basis. She hated me for that and so she was not kind to me.
Fast forward, she now wants MY comfort and support now that dad is gone. She wants to spend time with my son and is excited about the pregnancy. She is always texting and wanting to get together, but I just don't really want to spend time with her anymore. I've been supportive for these first 8-9 months, but I really can't take it anymore. She has been nice for the most part, but I really just hate her personality. I'm feeling guilt because I know that she is grieving and struggling, but she really isn't good for my mental health. This vexes me daily and I'm not really sure what to do about it. I dread the next time I will receive one of her texts. Not to mention, we just moved so I'm still stressed with my mess of a house, and some days the morning sickness is so bad I can barely function. She has offered to help me, but I don't like having her around; she makes me uncomfortable.
