Boyfriend and I didn't really have a fight

But whole story is that I got fed up with his friend calling me fat and I had a melt down and said I wanted diet pills.

Boyfriend came back with I should get anything I want even though it would put us in debt. Meaning I am a princess who always gets what I want.

Here's the thing though the only things I get for myself are shampoo, conditioner, body soap, and an occasional soda (once a week to keep migraines down).

I brought up that I never get anything for myself because I know we are struggling. And I don't deserve anything (my parents would beat me I'd I needed anything for school so I feel guilty for needing anything at all).

I also brought up that I hadn't received anything from him for Christmas or my birthday at all, and he seemed genuinely upset because he hadn't.

The friend who keeps calling me fat will do so in front of my boyfriend and he will not say anything to the friend and that is upsetting me as well because I feel like he is agreeing with him.

But one of the other reasons besides price ($50.99 for 90 of them,) is that boyfriend feels like if I get super skinny I will leave him.
