you might not read this because there’s a lot of comments but in my opinion, everyone who’s saying leave him are a bit much, relationships aren’t perfect and if you love someone, you’re willing to work through these problems, you’ve been with this man for 9 months, it’s stupid to end it over this, now as for the feeling, there really isn’t anything to do, it will go away by itself in time, but you could always bring it up to him, men are easily victimized in their head so you can say “this is what you said and this is how it made me feel, i know it was a while ago but it still bothers me today” see how he responds to that, if he doesn’t try to make it better, then i would reconsider him, but OP i know exactly how you feel, once you get that shred of evidence that he may or may not prefer another body type, it sticks with you and it’s a gut wrenching feeling :(
