Ok I want to leave a comment here. First of all you are worth more he could ever give u. No one has the right to tell you what you are allowed to do. Unless it might harm you or others.
Now with saying all of that I am in a relationship with a wonderful woman and she has a boy friend. There are days I am upset with it but we are all working on the relationship as a whole. I feel jealous so I talk with them and we work it out. I am over weight but told I am beautiful. I am starting to believe it.
There are lots of people out there to help you. Go find someone to help you
