TLDR: I invited a girl from class over to my instructors place, she acted very smitten / attracted to the idea or of me showing interest in her, neither of us followed up on the invite, now I'm feeling dead in the water. If she didn't follow up with me after my invite, I should consider that a no / not a sign of interest and move on. IMO: move on regardless as if she isn't beating down my door, I'm wasting my time right?

I invited a girl from my class to come visit me while I was pet sitting for our instructor.

To remain discrete, I sent this invite through slack / chat as not to broadcast my closeness with our instructor and to maintain his confidentiality, etc.

She asked me about it in person, was smitten, and was physically trying to get close to me / lean in to me during that whole class.

By the end of class, she was preoccupied getting some help from another floating instructor and since it was time to leave, I just got my stuff and headed out (so not to wait around for her, etc).

She never followed up with me about visiting our instructor's place, hasn't responded to a message I sent her about a new connection I made in the class being a good resource for her (they both use windows, I use a mac).

The question is: is this her indication of not being interested? Or is she just not showing interest enough? Or am I supposed to make another move?

She legitimately seemed interested and I totally get shy around only her (she's not stunning, but she's fit and I think I must be attracted to her owing to my nerves around her).

The attraction window may have open and closed here. It's nothing too too important really. I'm just curious after seeing her really show some interest. IDK I personally feel like I didn't act on things enough, but my understanding is, if you give a girl an opening / invite and she doesn't take it: next / move on.

aside: I'm also apprehensive about inviting her over to my place because I am embarassed by my flat mate / embarassed by how gross / slob he can be. I think I'm also insecure about how ugly our apartment furniture is. Like she'd care I guess, but there is no other date invite that feels organic to me. Maybe all of those are compounding to be my problem.

Any feedback / observations are encouraged.
