Search Results: should i tease her

I met this guy 3 weeks ago at a concert. I went by myself. His friends approached me and we ended up hanging out for the night. He flirted but never made a move. His one friend was drunk and got my number before I left for the night. Next day, his friend asked me out, I politely declined, explaining I had chickened out from asking the guy I was interested in for his number. The friend said the guy heard me telling another guy I had a boyfriend (I don’t, I do this when I’m out alone to easily reject guys). The friend also sent me the guys number and said he thought I should text him. I did. We texted everyday for a week and he called me 3 or 4 times to chat. First time he called he said he was not a good texter and preferred calling (if I was good with that). Throughout the week we got to know each other a bit. He made sure I knew he lives a few hours away (he is moving soon tho), and that he is 9 years older than me. The last call we had was ~ half an hour and went really well. He teased me and called me nicknames, said his friends thought I was really cool, and mentioned different things we could do together. He told me he was going on a trip that weekend and at a music festival the following weekend so he would be super busy. He told me he was just a call away before we hung up.
I texted him the next morning responding to something he sent the night before. I asked a question about something we discussed on the call and he never responded to the text. A week after our last call, I had not heard from him so I texted again. I said I might be able to make time if he wanted call me again sometime that week. I figured I was likely getting ghosted, so I mentioned if he wasn’t feeling it that I understood and it would be no hard feelings. He texted back a couple days later adamantly saying he definitely wanted to keep talking. He never called though, and that was about 5 days ago now. Should I consider myself ghosted? If not, is it likely he’s just not very interested?

Over the past few months, my colleagues have been ruthlessly teasing me about another colleague (we'll call him John). John and I are both in administrator roles, the colleagues who are teasing us are teachers. If we all go out for drinks, they tell me not to worry about getting drunk because John will drive me home. If I request that someone assist me with something and John volunteers first, I'll tell other colleagues who later volunteer to never mind because John is already on it and they tease me because I don't need them since John (emphasis) responded. They glance at each other and smirk when John and I are together and one even obviously lingered to eavesdrop during our conversation. They also bring him up in conversation a lot and one of them (his closest friend) was watching like a hawk when John and I were speaking in the hallway (though she was too far away to hear our conversation I think). None of the teasing or eavesdropping seems malicious. Most of them are very good friends with John and have worked with him for a few years.

I'm not sure how it all started. I suspect that a couple of the paraprofessionals (who aren't a fan of me or John) started a rumor and it eventually reached the teachers. Either that or the teachers are just trying to play matchmaker. The thing is though, John has been extremely supportive of me in some of the challenges I've faced this year, and in the last month, he's grown on me in a way that's surprised me. I'm seeking employment elsewhere, and wondering if, when I leave, I should ask John on a date. I'm not sure if he feels the same way though. I would say that maybe my colleagues picked up on me developing feelings for John over the last month, but the teasing has been going on for months, and when I first started, my colleagues told me they were intimidated because I was difficult to read (RBF), but once they got to know me, they liked me a lot. Do you think their teasing me is a hint that he has feelings for me too?
