My Hubby Bulimic?

LIke ok hes been really obsessive with weighing himself all the time , everytime he goes to the bathroom he is on the scale. and he told me before to make dinner before he gets home. wich i never used to do and he came home starving and always ate soemthing and then ate dinner too but now he doesn't even eat much at dinner says he isnt hungry. I think hes makin himself throw up, in both our bathrooms there are puke stains in the toilet, and i know he would tell me if he were sick and also if he were sick he wouldn't run up stairs to puke. like he goes to the bathroom after dinner but its like he makes sure im doing something so i wont go in the room when hes in there. One time he went in there im assuming it was to puke, and i went in the room to get jordynne a onsie cuz she peed out her diaper on the other one and he like jumped out the bathroom oddly fast. then the othe day he scarfed down lunch and wanted me to put the carseats in the car, but i didn't go outside because i still had to get the kids ready. he said he had to crap but he never went but i think cuz he really wanted to puke and i didn't go out to the car to put the carseats in so he couldn't do it without me finding out. cuz i kept askin if he was gonna go to the bathroom before we left and he never answered. his behavior has just gotten strange lately and it worries me i dunno what to do.

I had an eating disorder for 5 yrs spent a year in therapy so i kinda know these things like the symptoms etc.
well friday night wewent out i figured when he was drunk id ask him cuz he would probably truthfully answer. but he said that he wasnt bulimic, didnt really say why he wasnt or how he wasnt based on what i asked him, he was 172 in july 06 now he has been in the 160 range. the other day i went in the room to ask him something, i swear it sounded like he had puked but then i heard him peeing so eh then of couse heso n the scale right after i was ilke watcha doing and he said weighing himself, he is 158 now. he keeps this up hes gonna weigh less then me lol. but i jus thad a baby 2 mths ago , hes 5'10" .
does it sound like an eating disorder?
