I have a 12 week old baby. I haven’t had a good relationship with MIL for years - she and I are not close at all. She has a good relationship with her son (my husband), and will often see him when he pops round to see her (without me). She’s never once invited me over or asked me to do any kind of activity with her. During the pregnancy, she didn’t contact me once to see how I was doing. We had a big fall out also, due to an argument I’d had with my husband. I sent her some nasty texts.
Since giving birth, she’s made comments saying she isn’t seeing the baby enough, but due to my non existent and bad relationship with her, I’d never feel like popping in there.
I attend a hobby on a Friday where my husband looks after the baby. I found out that on Fridays she has been coming to my house secretly and seeing the baby. My husband has been inviting her. I am furious and feel like this has massively impacted my trust with my husband. AIBU?
