I'm new here, but guess I just want a bit of a rant. My bf has 3 dc from a previous relationship and lately I have just been feeling so left out and unhappy. We've been together about 2 years and I have met them briefly once. They all still do family days out together which I'm not invited to and there was one thing I really wanted to go to but I couldn't. It's just really getting on my nerves as I feel like I'm just a mistress. I actually do get on fairly well with his ex and we will text each other occasionally about bfs Christmas / birthday presents etc! What would you do, aibu feeling like this?
