does anyone feel not pretty enough sometimes?

my husband is a very handsome man, well put together, super polite very well spoken. friends and family constantly tell me how lucky I am and I know that I am blessed.

I'm no troll but I definitely know that he could have definitely been with someone way prettier than me. hes been at his new job for a year now and sometimes I struggle when hes at work because he works with a lot of woman who some are so beautiful. he a correction officer and works in the prisons.

I found out from some of his co workers that my husband gets hit on a lot at work especially by the nurses (hes never told me he gets hit on a lot) these girls know he's married but some of these girls don't care. I know my husband loves me, but sometimes I struggle with idea that he way one day want to explore something with one of these girls. it sucks to feel this way. we've been married 6 years and I already always try my best to always keep myself put together, i always try and please him sexually, always keep the house clean and just try to not be a nagging wife in general. basically I try hard to be confident in his eyes because I know he thinks that's attractive. I never want to give him a reason to look else where. I just feel like I'm not at his level when it comes to my looks😕

he has to work with woman and I have to suck it up I know, but how can I stop this jealousy feeling? any tips and advice?
