<human>: I've gained some weight in the past year or so. To the point where I feel very uncomfortable in my own skin. I used to be very active and into exercising but lately I've let myself go. I'm barely 5' therefore any weight change looks significant on my body.

Lately, this gain has been causing intimacy issues in our life. We live together so we always have the chance to fool around but I haven't wanted to due to worrying about what he thinks of me. 

He is very supportive, constantly compliments me and states how in love with me he is and how he is very attracted to me, yet I'm constantly second guessing it. Not because I don't believe that he finds me attractive, but because I don't feel attractive to myself, therefore I have a hard time believing anyone finds me good looking. He wants to be intimate and has tried to spice things up but I have ended up spoiling the mood by being uncomfortable, and causing arguments. He thinks that I'm using it as an excuse to not do intimate things with him, but it's simply because I just get so upset that I let it get in the way of any intimacy. 

I know I have to work on the way I see myself and be comfortable in my own skin but it's hard to do so when I feel like I'm letting him down.
