I need to give a lot of context here so I'm sorry if this is long. Also, it may be a lot of rambling that's all over the place so sorry again.
So I have a crush on a coworker. He's really nice, understanding, and we have A LOT in common. He would stop by my office or I would go by his and we would talk for the longest time about everything. He and I both just so happen to be really good at keeping eye contact so when we talk, he is usually staring at me directly in my eyes. There have been times when I caught his eyes wandering and there were times where our eyes would meet. For example, one day I was just coming to work and I was driving in the parking deck to the third floor. He had just got out of his vehicle and he locked eyes with me as I was driving up the parking deck. We both are a little shy around each other. We haven't touched once (meaning a gentle touch of the arm or a hug). Also he just recently broke up with his gf (like last week) so this whole time has been just he and I having friendly conversations (out of respect of him being in a relationship).
Well, today is his last day here (he is transferring to a new job). Friday, I asked him to stop by my office before he left for the day to say goodbye. He waited until the end of the day (when most of the office was gone) and came by. I told him how happy I was that I got to work with him and I'm going to miss him. He proceeded to thank me for being real and for being a good friend. I gave him a congratulations card. In that card, I wrote a little note that basically said "thank you for being a good friend. I'll miss you" blah blah. I also included my contact information. When I gave him the card, he told me he would read it later and not in front of me because that would be "awkward" lol. No text or email or anything over the weekend which is fine. Well, today, he stopped by my office and gave me HIS number on a note that said if I need anything to contact him. Weird. I did not expect that especially after I just gave him my number.
Am I crazy for thinking any of this stuff means anything? Should I use his number? Help.
TL;DR: My crush gave me his number unprovoked after I gave him mines in a greeting card. What does that mean and should I use it?
