Please bare with me

I've heard of males breeding themselves to death, and I think I have one that will. I bought him mid-last year, and he was a lean 1200g. We tried offering mice and rats every week to every two weeks. It took about 3-4 months before he finally ate (an asf at that). He ate well for maybe 2 months; then he began skipping and eventually stopped... winter hit. He's still off food and I'm starting to worry. His last meal was 12-31-09, and it was only one asf. He has grown longer and only weighs about 1100 grams now. He's getting thin. I feel he should be at least 300grams heavier. All my other males are back on feed. I've never had to deal with this. I'm thinking about tubing him if he gets much worse.

I've heard of moving the males to a different room. I'll do whatever is needed of course, but I'm hoping there are some tips or tricks that can be done without having to move him as I have new snakes quarantined all over the house atm.

I've also read where people have had males that wouldn't eat until the female they had been breeding ovulates. The girl he was breeding is building now... would it be counterproductive to put him back with her? She looks close... but I'm not sure if it will work for him.

***We did try to force feed him unsuccessfully last Thursday. I wasn't really comfortable with doing so, but we agreed we'd give it a shot. I know you're supposed to gently hook it on their teeth, but he'd just unhook it and run.

Any advice would be greatly appreciated!
