My partner has fallen out of love with me and moved into the spare room

DEAR DEIDRE: MY long-term partner has moved into the spare bedroom because he’s fallen out of love with me. 

He now only sees me as a friend and wants to split, but I don’t understand what I’ve done to make him give up on our relationship.

I’m 36 and he’s 40. We’ve been together for 12 years.

I thought we were so happy and that we’d grow old together. 

Everybody saw us as the perfect couple.
