My boyfriend fell for her cuz she's hot?!?

We'll it turns out the reason my boyfriend fell for anotherShe didn't return the feelings) was because she was hot.I know I'll never be confused for a Victorias Secret model but I didn't thnk I was ugly.We've been living together for 16 yrs. and he met a chick from the grocery store and became infatuated with her and started to write her love poems and even hand made her a trinket box, all because she was hot.So how do I get my self-esteem back and let him touch me without feeling afraid I'm repulsing him?Oh and in 16 yrs.he never wrote me a poem or hand made me a trinket box!
