PLusha, many hugs. itne maze maze ke khaney banao gi toh moti nahi toh kya slim trim hogi. hehehe 
seriously i think as mch as ur cookin is awsum, i think its also takin a major toll on ur health yaar…
i m v concerned abt ur prb. u said he verbally abuses u and stresses to mch on u to lose weight. if this is his attitude now, what if later u become pregnant and are unable to lose weight post delivery? his being perfectionist dusnt mean he has the rite to put u down and expect u to b the perfect doll with a perfect figure.
how r u even listenin to this crap really? for ur height u r at a gud weight!! actually perfect weight if i tell u. i m 5’5 and i shud be 62-63 i guess. iwas 68 before i got pregnant so yeah ive always been overweight so in my case 5-7 kgs was enufff. i think he is being v unreasonable.
plusha honey, i m tellin u once an abuser(physical, verbal) ALWAYS an abuser. tht is the bitter truth and u have to face it now if u wanna still get married to him. trsut me ultimatums and challenges wudnt work with him cus he is used to that. its like sayin ek dafa admi ka haath khul jata hia (physical abuse) phir woh rukta nahi. first slap, then punches, then kicks. same with verbal abuse, it wudnt stop.
if u r stressed rite now and u have every rite too, m sorry but u r gonna b at ur worst stage when u marry him. what happened to love being blind and not superficial for cryin out loud. if he loves u he will accept u the way u but at the same time coax u into losin weight. slow and steady wins the race. if he was sensible he wud have nicely pushed u into it rather than puttin so mch pressure on u. if u r like me and food is ur passion and u live to EAT, then its gonna b hell time for u to lose weight. its imp he understands that also. if ure used to certain lifestyle and eatin pattern, it takes time, u cant just do without it in a day!! just like he didnt becom a macho man in a day!!!
sorry for the rant but i m sooooo damn pissed at him for makin u sad. (HUGS) take care of urself and dun let him treat u like **** please!!
