AiBU to not being happy with 23 year old son moving back in with my partner ? Context we have been together 3 years, when first met, his son was at university, he then ditched university, before her last year, said she had nowhere to live, Dad said he could move in with him, . He moved in and basically took over (I stay over about 4/5 nights a week) washing late at night, not cleaning or washing up, smoking weed in his bedroom, very temperamental. He stayed a year and then moved out to live in a shared house, that ends this summer and now saying he wants to move back in with Dad, he has said yes. I was planning to move in and as my daughter goes to university, but now I’m reluctant as just want some peace. Am I being selfish too?
