Do you think I did too much? (Please read all)?

Long story short my ex boyfriend f*cked up, walked completely out of my life for three months for a tramp, they broke up, and he just recently apologized for it and started talking to me again, asking for friendship. I told him we're not friends because I don't trust him. He still calls and texts every other day, he texted this morning and we talked and a little while after I felt like I needed to talk to him about how I feel so I sent him a text saying "I feel weird talking again. Like I want to but I don't at the same time." I sent that text at 11:47 in the morning..he never replied and now I feel like I said something weird, do you think I did? I feel I had every right to tell him that. I just now tried calling him one time and he didn't answer so I left a voicemail saying "Hey I just wanted to talk to you about the text I sent earlier, so just give me a call back when you can bye." I will not call or text him again, until he replies and if he doesn't then I just won't talk to him anymore. Do you think I did anything wrong by doing this as in making myself look clingy or obsessive in his eyes? Thanks alot.
