Hi Dee and welcome to 3FC!
I am sorry your boyfriend's support is insults. No one deserves that. But luckily you have landed at the best place on the net for support, encouragement, advice and tips.
I understand a very tight budget but with careful planning, I believe, it can be done.
I suggest the following forums -
Diet Central - Here you can read and discuss various diet plans.

Fitness Forums - Everything about exercise and fitness is found here and if you can't find it, just start a thread about it and people are always willing to jump in and help out

And for tons of motivation and advice, check out the Success Stories here -

We are here for you and we believe in each and every person that is committed to changing their life for the better, including you. Now you just believe in yourself. We are cheering you on to victory
