So a bit of background. I'm 30. My boyfriend and I have been together since November 2017 but things are a bit complicated as I'm still waiting for my ex to agree to a divorce. I'm also waiting for an operation this year. My boyfriend knows that I really desperately want a baby but because of the operation and the divorce he doesn't think it's the right time yet, although he says he 100% wants us to have kids. In the past year three of my close friends have given birth, as has a colleague and now two more good friends are pregnant. He decided to tell me in a phone call as I was driving, and was staying away for work that his brother's girlfriend is pregnant. I didn't even know they wanted kids. She's always been presented to me as really career focused. I've never met her or his brother (I'm really shy and nervous about meeting them) but have met his parents quite a few times. It is his mum's birthday in May and I'd said I'd go to her birthday treat which is dinner at a steakhouse (I don't eat meat) and a theatre show. I wasn't especially looking forward to it, as it's not things I like and I was anxious about meeting the rest of his family, but I knew he'd want me to go. Now I've found out about their pregnancy I just really don't want to go at all. I just feel so upset and worried that it will never be me. I don't want to put a downer on things but I just don't feel like I could play happy if I went. I just want to bury my head in the sand. He's saying I'm selfish and should put my feelings aside for his mum's birthday. It's not like I'm saying he shouldn't go, he deffo should, just it's really not something I want to do or feel comfortable going to. Aibu?
