Is my boyfriend abusive?

I don’t want to jump to conclusions because it feels like I might just be in my head about it. So my bf of 3 years after his dad left really changed and I completely understand how hard it is for him because I’ve personally experienced it but, hes been very rude within these past couple of months. For example. Making little comments about my appearance. We will see a beautiful women walk by and he will point to her and say stuff like “this is who I should be with someone like her” I’ve struggled with eating disorders all my life my lowest weight was 110 highest was 206 my height 5”5 for reference now I’m 148 (steadily)and he tells me I “look fat” or I’m getting chubby I go to the gym and I’m vegetarian no processed foods since they are my “fear foods” but when I actually try and say maybe I’ll eat this thing I think is unhealthy he tells me I shouldn’t be eating that. He tells me he should be with someone who actually “has titties”. Just makes fun of my body constantly putting me down. But then sometimes he tells me how perfect I am and how he Dose not deserve me. It’s literally so confusing. But, the worst thing he’s done is when I told him I didn’t want to have sex because I had a migraine he told me he was going to go have sex with someone else and it’s literally humiliating to admit this but I basically begged him not to leave and ended up having sex with him anyways which was so stupid but I did it. And just today he accused me of having sex with my male friend which is crazy and I told him that but he basically screamed in my face calling me a whore it was very scary for me to see him like that. It looks like he was not there like it was not the guy I knew.
