How do I know if he still wants me?

Long story short;

I have a massive crush on a coworker back in 2019 but when I would out he had a girlfriend I backed off.

Ended up getting into a relationship that ended quite recently; he was controlling, manipulating, horrible person. He had his good days which I thought were great! I thought I needed to stay with him because I thought “no one else would have me”

(Still in this relationship) During this lock down my coworker got in contact with me and after talking I found he liked me when he met me and “still did” he said he maybe even loved me.

I escaped my relationship and I am in no way ready to jump into another one but I wanted to speak to my coworker and see if he still wanted me. We met up and he kissed me and since then has barley spoken to me and it’s made me feel that he doesn’t want me anymore.

It’s driving me crazy because I just want to speak to him but I feel if I message him it will be overbearing.

Does anyone have any advice on how to handle this or what would you do in this situation?
