Long story short: Dm has a new fella, he lives abroad, she lives a good 5 hours drive from me. I met him last time he was home, at my mum's house- he's ok, I found him fairly boring but not objectionable. Met him in total three times. He went back to his country but came back about a week ago. Dm and him seem to be inseparable, every time I phone her he is there and I feel like I can't have a proper conversation with her as she is different when he is around.
I phoned her tonight, he was there, they have been away for a few days. Normally at half term, she comes to stay with me for a few days. She asks if the two of them can come to stay. I don't have a lot of space so she said they would stay in a Travelodge.
The trouble is, I don't want him to come. I hardly know the man, I would like to spend some time with my mum and don't want to spend it with the stranger that she is when he is around. I feel like I should offer my bedroom and sleep in the spare room so that I am offering hospitality but...I don't want to.
I feel so unreasonable and childish, I'm 44 ffs. Do I need to get a grip?
