Hurt feelings over something stupid

So today was laundry day and i needed to wash my jeans because they are my only pair of maternity jeans and at the time I was wearing them so I took them off and out on some pj pants that I know aren’t to attractive but they were my only option.. so long story short my husband gets home and I said I really don’t look my best right now lol because I had just seen myself in the mirror.. and he says yeah I know but your still fuckable I rolled my eyes and laughed I said what is that, he said you’re like a 4.... my husband called me a 4. That hurt my feelings just a bit I mean I know I’m not that most attractive person in the world but I thought I was maybe a 6.5-7.. I said really you think I’m a 4, he said yes but not all the time most of the time you’re like a 6.. it hurts because I know I am not stuck thin I never have been and now with being pregnant for the 2nd time in a year and a half I have stretch marks and I wasn’t able to lose my weight from my 1st pregnancy before I got pregnant again.. and he doesn’t compliment me he used to tell me I was beautiful or cute or pretty now it’s nothing at all. We also don’t have sex as much anymore he would rather masturbate 2x a day.. it just makes me feel like crap knowing that he sees me that way..
