Sorry I know this is long but please I need advice

My boyfriend keeps saying that I need to eat healthy and need to fix my diet. I don‘t eat that unhealthy, the occasional treat. Plus he eats more junk then me. Worse part is I’m really sensitive about my weight and the way he says it and how he has started acting with me feels like I’m not longer attractive anymore. I’m no fat! I weigh about 85kg, I have big boobs and bum, I’m 5’6.

I have depression and I hate how I look but I’m trying to just feel better in myself and comfortable. He just has started acting so different towards me, I feel like he is losing feelings that’s why is trying to change the way I look. I feel so happy when I see him but then as soon as he starts to talk almost the first thing he has starting doing is talking about my diet.

Ive had such a shit day and I feel awful, he can even tell how much of a face I’ve been putting on for over a month cos I’m stressed and I’m so sad. Then he starts doing this, he sees that it makes me sad and upset yet he still does it and never seems to feel bad for making me feel like shit.

I don’t want to leave him but it’s been in my mind a lot recently which scares me. I love him but we keep arguing and even sex isn’t that good anymore. We probably only done it about 3/4 times this MONTH! Before we did it 3/4 a week a least!

Also I’m scared and happy coz I could be pregnant but it’s too early to tell yet.

Sorry I know this is really long but please I need advice
