My brother is 12 years younger than me and still lives at home, his gf is 21 and they've been together for about a year, she stays over nearly every night. I have another brother who is more my age who has a two yr old daughter and a baby boy. I have a 7yr old boy and am pregnant.
My brothers gf is a special needs teacher so would be quite keen on children, you would think. My niece gets left with my parents a LOT since the baby was born since SIL finds it hard to cope with two small children.
The gf is constantly posting pictures of Facebook of niece, saying how cute she is, funny sayings etc and is always commenting on SIL's wall about days out she has planned for her etc. My son adores my youngest brother and he is really good with him when he sees him, play fighting with him etc but they never take him out and wouldn't see him if he didn't go there once a week after school. When he does go to the house, the gf doesn't even acknowledge DS as in doesn't even say hello. She doesn't ask him anything about himself like how was school and I've never seen them having a conversation, she just ignores him.
I saw her today and asked her a series of questions about how she was, was she enjoying the holidays etc and she has never once asked me a single question back. I'm pregnant FFS, it's not hard to think of conversation with me. I was showing my mother my scan pictures and gf didn't even look at them. She has so little interest in me and DS.
I think it's all the public gushing about my niece that makes it worse. I just think she could say hello to DS, it's really rude.
I have three SILs in total and get on with all of them so I don't think it's me.
