Am I ready ?

Hi all! After 12 years of being married, I got out of it in December 2018. I gave myself time to get back on my feet again still had a lot of one-night stand kind of fun but nothing serious at all. Recently, I got this feeling that I am terribly afraid of being close to someone emotionally. Like every time in a date, someone wants to be romantic and starts cuddling or showering me with a lot of romantic moves, I get so uncomfortable that I come back and never call them. I think all this is a big lie and everything is just about sex!!! I know this way of thinking Not normal. what do you think I should do?
