My boyfriend (22M) wants me (19F) to gain weight kinda against my will, am i the problem?

So, to give some backroud, I was always a bigger child and at 13 a lot of weight went into my thighs and chest. My family always told me to lose weight, so i did, dropping from ~80kgs to 40kgs. As my weightloss was really fast, it was not healthy whatsoever. Went into anorexia recovery and got better yay

Over the years i gained 15kgs, so that makes me 55-57kgs on a normal day (im 160cm) I go to the gym regurarly and am a pretty active person. I’d say Im pretty healthy. And finally kinda happy with how i look. I’m able to eat pretty intuitively and not stress about it. So now to the meat and potatoes…

I’ve been with my boyfriend for a year and a few months. When we got together I was struggling with a bullimic relapse and he helped me through it. He is into thicker girls and a few moths back started talking me into gaining weight, about 10kgs. He talks a lot about how i’d have the perfect pixar mom physique, how my thighs, boobs and ass would fill up and i would look awesome. At my heaviest, my boobs were indeed, huge. F-G cups.

Gaining weight has been really scary for me, talking about my body really stresses me out. I hate the thought of going back to that feeling of disgust everytime i look at myself, but i really wanted to make him happy so I tried to eat more and start gaining weight. It wasn’t going well, I was, and still am stuck at the same weight, so i’m starting to count my calories just to insure I’m eating enough.

Now, I do wish to put on some muscle mass, but the pressure he puts on me with the GAIN WEIGHT type thing is stressing me out. I feel like i’m finally in a healthy place, where i do not feel the urge to puke my brains out. He is really adamant that i should gain weight, that i’f be much healthier and how i’m robbing him of the perfect thick girlfriend. My emotions are more and more mixed by the day, it makes me feel like he doesn’t like how i look now and just wants me to be just what he wants, even though i do not want it as well. As i said, i do want to bulk, but not that much, not that fast, i want it to be controlled and preferably, i would like to just eat at maintenance and gain muscle👍 We made a deal that if i gain 10kgs by April, he will buy me a lego i really want.

His family keeps telling him that he should be unhappy with how i look, that its my body and i should be the one happy. I feel conflicted, as i really love him and want him to be happy but at the same time i feel weird about how he keeps going about this gain weight thing, how he makes it kinda about himself.

I wanted to provide some pictures (before i lost weight and now) but i cant lol so please tell me if im the crazy one for not wanting to gain weight… we talk about it a lot, it has been a topic we fight about sometimes as well and i cannot stop thinking about it all. Thanks!!!!
