How to end things

Ok. So a bit of background, I’m 25 and my boyfriend is 27. He has two kids and I love them dearly, but I feel like he views me as a babysitter and we haven’t even been together 2 months and I feel like I shouldn’t have met them so soon. I have an autoimmune disease and live with my parents because I was laid off, and they don’t want me to leave the house and risk getting the corona virus. My boyfriend says I’m using my health as an excuse to not see him and has been exhibiting A LOT of manipulative tendencies since the stay at home order started. Today, I get this message from him.

His is in black, mine is blue, for clarification. Guys, how do I end this. He has my debit card and a few of my things and I don’t know what to do. A few nights ago, he flipped out on me and I’ve been terrified he will just show up here and I want to end things. Please give me advice.
