Was I wrong for trying to make things right after he wanted space?

This is a long story but I’ll sum it up. My ex and I started seeing each other again. He gave me a lot of mixed emotions and energy. He would say he’s not dating me then do dating activities like taking me out to dinner, watching movies at night, we started seeing each other every day. Then sex got involved. I waited over a year to have sex with someone I wanted to be with and it hurt when we had sex again and he wasn’t sure what he wanted. So I asked for space. He proceeded to talk to me anyway, I took care of him a lot bc he’s very sickly so I felt obligated to be around to help bc I love him. I was very confused bc he’d express his feelings for me then go back on it. I would cry a lot but one day I finally stood up for myself and told him this has to stop because I don’t deserve uncertainty. We actually had an argument and I haven’t argued with anyone in a long time so it took a tole on me. He wanted space and I told him I had a back brace for him that I wanted to give to him for his scoliosis he suffers with too. He just stopped talking to me abruptly. I still dropped his back brace off at his door with a note saying I’m not mad and I still love him no matter what. He still proceeded to ignore me (which was something he did in the past which made me want to leave him). I sent him a message on how what he has done hurts me. He got really hurt by that and I tried to make it better. I told him that I just want to let this go and move on and he got overwhelmed from me reaching out as much as I did. It’s been over a month since the argument and no resolution has been made. Am I wrong for what I did?
