Gaining

Should i gain weight?

My weight has fluctuated throughout my life but I was never even really "chubby". I was for the most part skinny, however, I did end up getting pretty chubby recently and I really really liked it, but my girlfriend didnt. She knows that I have a weight gain and fat fetish and she is trying to gain weight for me while I am trying to lose weight for her, however, I felt alot better when I had that excess fat, and I really wanted to keep gaining.
Should I gain it back or what? I know my girlfriend would still love me no matter what, so that's not even an issue, but knowing the situation, what would you do?
