DP has taken our 14 month old out today, with his friends (dad & there kids. It's a rare occurrence. I hurt my back this morning with DD at the park (injured a while ago prone to setting it off sometimes) it's not horrendous but it is annoying & uncomfortable. So I've been on the sofa taking ibuprofen, catching up on some TV & chilling out. FOR ONCE. But before that I did tidy around. Dp just called & said his mate is coming back to have some food with his kid. This is the AIBU... I didn't say no, I can't say no his an adult. But I did say ahhh ok. He sensed my lack of excitement (I'm in my pjs here really didn't anticipate house guest especially when I've just tidied up) he just said 'yeah yeah don't worry, I'll just tell him to fuck off' & hung up... I messaged him saying I didn't say no & he can come for dinner I just wasn't expecting it. He didn't reply, tried to call back & he didn't reply. I know this is gonna turn into a row when his home now & honestly I can't be arsed. AIBU?
