Hmm... I agree with the above. It sounds like you're going through a hard time of things.
And, more than likely, it sounds like you're burnt-out on the Amiga kommunity. It happens to everybody. Lord knows I've been sick of the nonsense enough times throughout the years. You might consider thinning out the Amigas a bit, but I wouldn't sell 'em all. In a year or two you'll get that urge to tinker with them again. Then you'll want to find someone else who understands, and you'll end up here again...
So put the Amigas up on a shelf for a little while. Spend some time with the girlfriend, and do some things you enjoy.
Don't sell the systems because you'd probably end up kicking yourself over it later when you want to tinker again. (And it's hard to re-assemble any collection you've sold before. Trust me.)
