Firstly I want to prefix this by saying I love my partner. I have children, he doesn't. We have no plans to live with each other. We see each other two evenings a week plus part of the weekend. He is completely miserable without me though and i think deep down he wants someone who is more available to do things with him, normal couple things during the week.
I'm busy with children and work so i have no more time than this. We are in our early 50s. We love each other hugely, get on with the respective friends/families, genuinely really happy when together but I hate that he's permanently low without me/when he's not busy. I don't want to break up but is this workable?
