A few months ago I started talking to this guy that I met at work. I just turned 20 years old a few weeks ago and he's 27

We both got just got out of relationships. he actually just got divorced about 6 months ago. his ex-wife was quite a bit older than him around 15 years. he told me that he wasn't looking for a relationship which I wasn't either.

In our many conversations that we had he told me that his wife had medical conditions and he hadn't had sex for about 4 years due to her medical issues. I've never asked him what those medical issues were considering if he wanted me to know he would tell me so with that being said I know he probably wanted sex from me which we have never technically had intercourse but just a few days ago I gave him a blow job which he seemed to really like. It's been a few days since then and now he's acting kind of weird, kind of distant. I will text him just to have a conversation with him and he will answer my questions and then go silent. I've seen him at work since then and he seems to be kind of normal with me he will have conversations with me but he won't bring up what happened between us. During our sexual encounter he told me that he thought I was so beautiful and then after he wanted to know if I wanted to go get coffee with him which I declined. I don't know if I should completely stop talking to him or give it some time as he might be confused with his feelings I'm not 100% sure! I really like him also!!

What should I do?

Update: I decline the date because I had an appointment to go to and I explained that to him!
