<human>: Could you distill the essence of the text into 1-3 sentences?

I have a crush on my TA(25 M) he's a master student and I'm(22 F) a second year uni student. I really want to get to know him better but I'm scared shitless of rejection. 

I can't tell if his friendliness is because he's my TA or because he's also interested in me. After classes we normally talk, we walk out together and he walks me to my car before he hops on the bus. Other than that we don't communicate out of class.

I have a stupid suspicion that he's probably 'out of my league' which is why I have never said anything to him. 

What do you think though, reddit? Should I stop crushing or should I gather my courage and go for it?
