My partner and I live together, he has a 13yr old daughter who I have always gotten along with and had no real issues prior. She stays with us every other weekend, she is definitely 13 going on 30 and although I have seen her sassy, slightly ruder side at moments I’ve never had it targeted to me.
We recently found out I was pregnant with our first child together, we mutually agreed that my SD should be the first to know to allow her to process her feelings before we shared with the wider family. My partner sees the good in everything and was adamant she would take it well but I was apprehensive given her age and that there is already jealousy between her and her younger cousins. She has often mentioned that my in laws do not make as much effort with her vs other children in the family.
I thought it would be best my partner tell her one on one so that she felt comfortable to voice any worries as she was feeling them. Later she got upset and told me as she felt understandably worried that her dad wasn’t going to make any effort with her anymore and he was going to forget about her. Not only did it upset my partner but it upset me as something we were so excited about was causing her so much worry and upset. We had a girly day the next day to reassure her it was going to be okay. She soon said she felt she was being silly as she was worrying for no reason.
Since then we have shared the new baby news with my partners family as well as my own. However this is where the issues start, anytime my in laws mention anything to do with the baby she starts to act up, talks over people (about unrelated things) or anything will do that will provoke some attention. I said very little but just asked my partner if everything is okay with her as I don’t think she has as on board as we think she is. I try to keep conversation about the baby to a minimal when she is staying with us and I’m worried it’s going to upset her further. She has recently starting making little comments when my partner isn’t around like telling me he broke up with his last girlfriend because he didn’t want a baby so soon (which is not true) or telling me that his grandmother said if it’s a girl to return it (there are a lot of girls in the family and it was made as a joke but she didn’t mention that part). The last few weeks have been really tough, everything or any choices I have make (things since as new plates I bought for our kitchen) seem to be in the firing line, they are stupid or ugly. Her behaviour in general has just gotten much worse in the last few weeks, she will be extremely rude to my partner and his parents, but he doesn’t raise it with her. Understandably he doesn't want his weekend with her to be a negative one but this means she thinks that is now okay to speak to people like that because she’s being allowed to. My partner is still adamant she is excited and happy about it, but I am really not convinced. We have each other on social media and she normally is very active interacting with anything I post but anything baby related she will not.
This weekend I was given the cold shoulder and ignored any time I spoke or given dirty looks. Which is the first time I said to my partner that enough is enough (the raging hormones, mean I have less patience than normal) as I live in this house too and don’t deserve to be treated like rubbish. It’s causing me so much anxiety as I don’t know what to expect when she arrives, I’m worried about what the future looks like as it seems to be getting worse and I’m worried it’s going become a serious problem once the little one is born as inevitably a baby is going to get a lot of attention. I have made it clear to my partner that her current behaviour wouldn’t be acceptable around a younger child which he has agreed. He hates confrontation and to be the bad guy so I have little hope that this is going to improve.
Please help me, I’m trying to have patience but if I’m truly honest I seem to have none with my pregnancy hormones. I do not have much experience with blended families and neither do my friends, is anybody able to give some advice?
