What to do in this situation?

So there is this guy. He’s my instructor for my ground school flying. He’s only a couple years older than me. It seems to me that every time something goes wrong with his devices he always mentions about having an electrician to help him *which is what I do for a living. No matter if the whole class is in there or not. For my first test it was just me and him in this building afterwards we started talking like nothing too crazy. Then he asked me what I was going to go do after this and I told him I was going to shoot my bow. Talked about that for a bit then I asked him and he said he was going to go fly. I didn’t want to step on any toes as I didn’t want to be desperate unless he invited me which he didn’t. Since then he’s been playing hot and cold. Last test I had to go in again and he helps me a bunch, but didn’t make much eye contact with me but he did fidget with his neck. Couldn’t talk for a while as he had another student. He has helped me so much and I texted him to see what we did this past week in class. He told me what we did and then asked if I wanted him to find me a video. I said yeah if you don’t mind. Thanks! And he sent me a video. I didn’t respond because again I don’t want to be desperate but I will thank him in person. I haven’t found anything about a girlfriend but how would you casually ask a guy for drinks considering he’s helped you with the tests just in case he does have a girlfriend? *But to me it’s seems like he’s interested but doesn’t want to come off too strong as I am still his student*
