I’ve been seeing this guy..

Okay, so I never done this before but I need some advice..

So currently I’ve been seeing this guy for the past 8 months, it’s been going really great, we met through a mutual friend, and we really hit it off right away. In the beginning he used to call me beautiful, and sexy, and love it when I sent him selfies , but recently it changed he criticized my weight a lot , every time I tell him something he seems like he doesn’t believe me at all, I don’t know what change , but it’s been bothering me lately that he calls me fat, and I should eat less, and everything, I really like him but his thoughts about is starting to hurt my feelings, I don’t know what to do anymore..
