Sounds like you are in a nice relationship conducive to gaining I say go for it.
I have a thing for fat guys and find them very attractive too.

This subject is close to my heart because i lost my guy of 8 years over loosing weight.
It was health reasons and I had to lose a lot and he had a hard time dealing with it.
I did too because I loved being heavy soo much but I have managed to work thru it.

I'm glad he still finds you attractive and is still in love with you so maybe you can work it out.
I hope so anyway good luck.

Being a switch hitter I love girl bellies too.
Nice and plump is a huge turn on for me.

Time to let him go if he only is attracted to you for your weight.
I'm sad for you that is just not right.
