Romance problem (SOS)

  I always get confused when I see people in love. Simply because I've never experience the real feeling of it, and it is hard for me to love or be loved which has been a big issue for me since I have been in a few toxic relationships. 

 I know this guy for quite the time, we get close easily cause we got the same mindset and all that. He confessed to me first, and I admit that I do have feelings for him. For me, this is a problem.

 I never liked someone like this, it is different from my past relationships and I am scared. He told me that he liked me but I can't make sense of it :(. What does he like about me? He did say that we just.. 'connect' and all that, but what does he actually ACTUALLY like about me? Is it the fact that I'm older than him? A few colleagues told me that I have a great face, is that what he likes? Or is it the fact that I always greet people with great intentions and some class? I could never make sense of it. 

 I don't know what he likes about me and I just can't find something that is appealing from me that would attract him. 

 I am also confused, what If I changed and not become what he knows about me? What if I am younger than him? What if I don't have a great appearance? What If I don't have any class at all? 

 Should I ask him these questions? I don't know what to do...(；′⌒`)
