Why does he show interest, but he does not ask for a meeting?

For a few months now I have been in regular 'contact' with a man. The contact is limited to a professional framework. He works in a self-service cafe next to my work and I've been a regular customer for years. After a few bad relationships in the last few years, I've noticed for some time that he keeps trying to talk to me again and again. This has been going on since about April / May until today. The conversations also become more and more private, personal and seem to stay with him as well, which I recognize by the fact that he chases and asks for days and weeks afterwards. No matter how much stress is currently, he always takes the time… Also noticed is that when I sit in and work on the laptop, that his eyes wander without talking to me again and again and the days he is when he was finished and actually almost out of doors came to me again 'just' to say goodbye to me… Noticed that he is looking for the contact ists me pretty fast. Only it is simply irritating for me that he shows so the interest and the questions are really getting more personal, but he never asks for a private meeting… Because there are already but now 9 months conversation exchange… But I have to say too That I'm characterized by a negative experience that happened exactly 4 years ago run pretty negative. It strikes me as the situation is also difficult to engage in these discussions. It's not that I'm uninterested. Actually not at all. But as long as I do not know wiener really stands or whether it is pure flirting I can't open so far that feelings can arise. And clearly I have already thought that this restraint may come across as disinterest. Am I really misinterpreting his interest? What other reasons could it have? He does not really seem shy now… And he does not talk so intensively with every second customer… Of course I'm not there all the time, but here and there it's already…

You will have to continue speculating forever if neither of you takes the next step. So easy.

"Because there are already 9 months"

A man who does not ask for a meeting for 9 months has no real interest.

He certainly enjoys talking to you in the cafe and likes to flirt, nothing more.

Have you ever talked about past relationships or seriously about love?

That would be a beginning to get behind it.
