I’ve been with my partner since 2007. I’m 37, he’s 59. We have no children together but I have a 16 year old that lives with us. Gradually over the years we’ve drifted further apart and yet I’m still absolutely terrified of telling him I want to break up. A few years ago we split up and he was threatening suicide. He’s pushing 60 with no relationship with his biological children so I feel immense guilt, and yet I’m slowly drowning in fear and desperation.
