I love my boyfriend but I’m scared our relationship is toxic

My boyfriend (TM16) and I (F15) have been together for 8 months long distance but have known each other for 4 years. Our relationship in general is pretty good, but the past few months he has been more angry and we have fought even more than we ever have. Tonight he yelled at me for not making my bed saying over text “JUST MAKE THE FUCKING BED ALREADY FOR FUCKS SAKE” and then told me after I started getting upset and crying he told me how “you have no right to be upset or cry, I was simply trying to get you to make that goddamn bed.”

I have OCD, and on occasion I have episodes or spikes, where I am very sensitive and anxious and stuck in my head trying to handle intense unwanted and unpleasant thoughts.
This week I have had 4 episodes, mostly at night. I always tell him when I feel I’m about to have one, when I’m having one, and after it is done. This I believe is completely okay for communication of what I am feeling and going through. He isn’t really able to help me in these situations so he always checks on me afterwards. Last night I had an episode that lasted for over 3 hours, I barely slept, was on my period, and have been very stressed due to school starting. I told him all of this, and waited for hours for him to respond, to which he told me I would be fine and to just make my bed so I could relax the rest of the day, and to text him if I needed anything. I understood he was busy at that moment but I felt upset he didn’t even ask how I was doing, and that he waited for hours to even respond that way.
I love him so much but he is often frustrated and yelling at me on FaceTime about the smallest things, blackmailing me with my secrets (this has happened twice already), and begins talking about how I did these things ive never done, which on occasion can make my ocd spike. I always forgive him but it hurts more and more and he refuses to open up to me. I don’t know what to do, but I don’t want to break up with him or hurt him in any way.

Is this becoming a toxic relationship, and is there anything I can do to fix it? He is truly the one I want to be with and I love him more than anything so if I lose him I don’t know what to do
