Im 21 he's 32... too old to date?

Since he is a former and not a current proffesser there should be no conflict of interest. However, the age is rather big, your generation is different and it may be hard for you to understand him and vice versa, he may just view you as a kid and not give you the level of respect you deserve, seeing how he is a seasoned proffesional. His attraction may on a pure ual level, you never know. From an experience my cousin had, she was in the same situation and went for it, it turned out to be a horrible experience for her. Having his stature as a proffesser he attracted many ex students and ended up basically cheating around on her due to his "power" as a proffesser. I think it would be a very very difficult thing to manage on both ends of the relationship. I will not go so far as to say it is completely impossible, but it would take some exceptional dedication and flexibility. Best of luck to you whichever you may choose, just know your choices have consequences. Make sure you can handle them
