I got along with my partners family for 4 years before we had our baby. My baby is 1 now and sees her grandparents every couple months. When she was a newborn it was every few days but eventually my boyfriend’s mum stopped coming over. Something happened which I wasn’t very happy about, some last minute plans my boyfriend had to go to (we were told the day before) and he works on and off 6 out of 7 days and this was a weekend where he had 2 days off, this just meant I would be taking care of my baby on my own the following day which I was pretty upset about as I was really looking forward to having 2 days just us as a family since it’s usually just the 1 day. I sent his mum a message just saying in future I’d be grateful if you could let me know more in advance as I have to then do everything solo. It was more detailed than that but either way it was a nice message just wanting a heads up next time, not the day before. I don’t get any help with my baby other than my boyfriend (her dad) so I really do look forward to having an extra pair of hands - which I feel like his mum doesn’t understand. Her response to my message was “fuck off”. Just plain and simple, to say I was shocked was an understatement. She’s quite known to be rude but I didn’t expect that, purely just for the sake of her son and grandchild. I deleted her and blocked her number. I then shared a TikTok along the lines of “no respect for the mom, no access to the baby” and this then got sent to his mum via her family members that I have on there. She then messaged my boyfriend saying “I’m throwing shots at her on social media” and that she now doesn’t respect me at all and wants absolutely nothing to do with me. No apology, nothing. My boyfriend spoke to her and said it wasn’t right for her to reply that however he also thinks I shouldn’t have messaged in the first place and that we all “played our part”. He was willing to break up with me if I tried to stop her seeing our baby. She’s now seen our baby twice since this has happened and both times I’ve been pretty upset about it. My boyfriend takes our daughter to her house and I hate being away from her anyway let alone around people I know hate me. Is there anyway I can prevent this, would anyone else allow this, am I wrong to want to stop her seeing her grandchild?
