Sunitaji,
yes, it is d right of the wife to get maitenance from her husband.
y ppl marry and then feel burden to maintain wife and children of their own.
escapism it s a psychological disorder.
fight, u hav not deserted him, it is he deserted u with out any reasonable cause.
proof of his income required, but when not able to get it.
u & ur child will get minimum maintenance according to the standards of d family.
ur advocate will look after that lacuna.
good luck.
