Is it normal or is it too much to tell him this?

Recently, my bf ish and I had a talk and released mostly everything thats been bothering us especially me. I just have so many insecurities with him because of how he sometimes acts with me. He gives me a reason to be suspicious.

However, I'm the one with the most feelings especially since Im the one who always brings up a problem and tries to solve it. When it comes to him, he never really brings up a problem he has with me. And i doubt its cause I'm perfect but its probably because he doesn't have as strong feelings for me so he doesn't care that much to even bring up what's bothering him. Then I asked him what he does like about me and what he doesn't. He straight up answered why he does and took a while to answer why he doesn't. I, on the other hand, straight up told me what I don't like of him and took a while to answer what I do like about him, actually I didn't even answer. I just said, "I don't know, I just like you." I guess I focus too much on the negative things that I knew what to answer and I don't focus too much on the positives. When I took a while to tell him why I like him, he was like "wow okay great..." as if he was convinced I don't like him. But he has no idea how much I do.

So now I'm freaking out that he thinks that. I basically asked myself why do I like him if he causes me a lot of sadness. But I wrote them down in my head and now I know why I keep driving myself crazy. I want to just shoot him a text with a list of things I like about him. Like "hey remember how you asked me what i do like about you and I couldn't really answer? well I realized why. It only took a while because I know I like you but I was upset at the moment..." Do you think its too much if I just tell him randomly and in a cliche way? I say cliche because I really wanna be honest with him and tell him that one of the reasons why I am crazy about him is because I feel like he's the guy I drew in my head. But idk if he'll take it like its too late and I'm just making it up or like I'm clingy and obsessed or maybe he will appreciate it. Not sure but I would love him to know exactly why I fight so hard to make things right with us.
