Now that the summer is ending, the project will be put on hold until next year and I won't really have a reason to interact with him anymore and I am sad because I won't see him any more. I kind of hinted at getting together for a drink again and he said "yeah we can figure it out later". I don't have his real phone number (only work number), so I feel awkward texting or calling him. If he hasn't made any moves does it mean that he isn't interested? After months of build up, it kind of felt like things were finally falling into place and that maybe we would stay in touch during the work hiatus. I don't want to put myself out there too much, because I'll have to continue to work with him, but I also don't want to stop talking to him.
Is he interested? What can I do to try to see him again in a non work setting?
