<human>: Me (20) and my boyfriend (25) have been together for a year and a half. We are currently in an LDR (I'm in Ohio, and he's in California.) I'm going to be going to college in his area and I leave in one week to be with him. We have met before, I spent two weeks with him last summer.

We don't really have any other problems in our relationship, and for the most part we are happy. But the closer I get to leaving, the more insecure I begin to feel. I'm a pretty big girl (5'5'', 275lbs) and he's an attractive guy (6'3'', 200lbs of pure muscle). He has never made me feel insecure, and constantly tells me I'm beautiful/sexy, always wants pictures, and tries to make a real effort to make me feel attractive but I just don't... and it's destroying our relationship. Last night we got into a really big fight about it, because he blames himself for me having such a poor self image when it really isn't his fault. It's a personal problem that I have with me.

Basically last night the point of the relationship was that he feels like he can't make me happy because he can't make me feel attractive, and with the deadline slowly closing in, I'm not sure what I could possibly do to try to fix this problem before I get to his house and become a mess and not want him to touch me because I feel so gross. I'm not sure how to fix this, and I need your help, r/relationships.

Can you condense the text into a few key points?
<bot>: i have poor self esteem, boyfriend blames himself, going to be basically living with him in less than a week, and insecurities are destroying our relationship. What do I do?
