For the past couple of months I have been having music lessons. The teacher is an attractive young woman, some 7 years younger than me.

From the very beginning we had good rapport and we got along very well, me making jokes once or twice every lesson, mutual smiling, mirrored body language etc.

While I did not make any moves in the beginning (there are many attractive young women around, not that many teachers for this particular musical instrument), gradually I did begin escalating a little bit with kino.

Eventually I found out she's in a LTR for several years now, and stopped making any moves. Lessons went on just as nicely as before.

A couple of weeks ago, when I arrived, I noticed something was off with her, and so I asked if everything was alright.. well, long story short, turns out the BF is bipolar, and has been mostly depressed for the better part of the last 2 years.

Apparently he's very sweet one day, and wants to get rid of her the next day, and this had been happening with some frequency recently.

She was now looking to move out, and rent a room.

I remember in that lesson (this confession was in the beginning of the lesson) she touched my hands to correct technique/posture for 10, 15 seconds at a time, while looking coyly at me, at the same time explaining what I was doing wrong .. this never happened before, some touching for sure (sometimes it's really necessary), but this seemed very prolonged.

Maybe, I thought, I'm imagining things.

Well, we stayed in touch a bit more than usual over email that week, where I casually dropped that we should go and spend some time together that weekend .. to which she replied she was busy with music stuff, but that it would be great and we should set it up "one of these days". She seemed genuine.

Well, another week goes by (no further email communication) and it's time for another lesson, so after some initial chit-chat I ask her "how's life" (the bf situation).

She says "everything is normal" and that things are ok .. but also mentions that she doesn't want to go live abroad (some weeks earlier she'd mentioned that they were thinking of moving abroad perhaps next year) anymore with him, because "what if he does something similar again?"

This struck me as a pretty crappy foundation for a relationship, and I suppose I missed the chance to ask her then and there why she's even together with him if that is the case.

The lesson went on as normal, and when it came time to say goodbye, I escalated another tiny bit and grabbed her waist (not the norm here) with one hand as I kissed her goodbye (this is normal m/f). She didn't object, flinch or move away, if anything she seemed vaguely pleased, but that could be my fertile imagination.

Either way, the last thing I remember before getting out of the room is her smiling.

Some other things worth knowing is that we play a lot during the lessons as well, sometimes I hit her playfully in the head and things like that, it's all good fun.

So far so good, right? I would say all of this together paints a very favorable situation.

Now here's the thing: I've asked her on a couple of occasions beginning already a month ago to install a simple messenger app on her phone so that we can be more in touch (i'm no keyboard warrior and my wifi is off 99% of the time, but it would be much more practical, to say nothing of secure, to use this app instead of cleartext email which I only access on my workstation).

She never said yes or no, just goes on without installing it. I've reminded her a couple of times, as I said, and she says she "will get to it" .. except it never happens.

Furthermore, she did not offer any follow-up to that email she sent saying we should go out "another day" - basically up to this point (a few months) I have only ever seen her in the context of the lessons.

I'm at my wits end and would like some opinions here, she's really cute and pretty and I really like her personality, and for sure I feel an attraction. But in order to see if it would be worth pursuing anything more, I need to spend more time with her.

Almost everything points to her being interested as well, but the chat program and no email follow-up makes me doubt whether this might actually be the case.

Any helpful suggestions or insights?

Thanks.
