I am beginning to think my partner may be in love with my 18 year old daughter!

I have been with my partner for two and ahalf years now. I knew him before as friends for over 12 years. He had his problems and was a heroin addict for 15 years but became clean.

He will do anything for her. At first I thought this way lovely, she has a good relationship with her dad but for my partner to be so fond of my kids was great for me as a mum. But about a year ago I began to feel that something wasn't quite right. Before I

I would watch the situation closely but not come outright and say it but it you do catch him with your daughter or something I would have your daughter live with her dad and help him get a job and and a place to stay then kick him out but that's me hope that helps
