I'm completely assuming here but where you're living together at the minute, you own it? You need to both sit down and talk about it and you need to hear each other out. 20 years is a very long time to just turn and say to go so has it been brewing for a while or is this a recent thing? Either way, you need to be clear with him and listen to his side of it too. If you've simply just fallen out of love for what ever reason, he needs to know why; it's the least you both deserve.
