Ugh! Some people can be so immature. He really should let you know if something is bothering him, but in the meantime I think you should just continue what you’re doing- be yourself. Continue to say hello and smile when you pass. Pretend nothing is going on. Even send a Christmas card. Don’t let him win this ridiculous and childish battle.
I really would love to pull him to the side to say WTF? I am generally a very pleasant person and would never do anything on purpose to offend anyone. I was raised to be professional and pleasant at all times even if you are having a bad day. Him being a highly educated adult and acting so immature about the whole situation really is kind of funny. I may just give him his Christmas card and put a little note inside saying “if I’ve offended you, please let me know”.
Some people exist only when they are in a fight with someone. Maybe this guy is like that. This situation happened to me - this girl was angry at me but she never told me why. She’s had fights with everyone, so I guess that’s just how she is. I gave her tons of opportunities to tell me what was going on and she never did. So I gave up. She seems to be an unhappy person, and I find it kind of sad.
Having a PhD in psychology doesn’t really mean anything, I can tell you! I think fixing your own problems is very different than helping other people to fix theirs. My brother is going through a divorce right now, his wife is a psychologist. The number of stupid things she’s telling him is just… :wall: I think she’s just very troubled, and doesn’t realize what she’s doing. :shrug:
You’re right, having a PhD in Psychology doesn’t mean that they know how to fix their own problems. It’s just so weird because he was never like that before. Oh well:shrug: , it’s all up to him now.
Be the better person. Send him a card. Don’t expect one back. Either he obviously has a problem that he is unable to voice with you OR you are reading into something that isn’t really there. I had a similar experience once and it ended up being nothing. Just the other person being unobservant and dense.
Well… about what your friends told you, is that only rumors, or do you have proof of that? I would say to be really careful about rumors and over-interpretation. It can make things way more complicated than they are! Basically, it seems to me you have no idea why he reacts this way, and maybe you will never know. I think it’s probably better to just go on with your life, and if he wants to talk to you, he will. If not… so be it. He has his reasons, and at some point, you have to respect that, in my opinion. Stay civil and polite, it’s the only thing you can do. 
No, I don’t have any proof at all that this is or isn’t true. It’s strange because neither of the two people I talked to about the situation do not know this man, do not know each other, nor do they work at my school. So for both of them to come up with the same thing about him possibly liking me is really bizarre:?? .
You’re right about me possibly never knowing the real reason behind his strange behavior as of late. I may never find out. But I will continue to do what I have been doing which is be polite and civil.
I agree with iza. Just go about your business, and wait to see what happens…if anything. Set your sights on your own personal goals, and life will be easier. 
Hi guys!
Things are back to normal now. Apparently there was some sort of misunderstanding on both of our ends. I just went about my business until he approached me this morning while I was waiting to speak to the VP of the school. Neither of us went into detail about what happened. But it seems to be straightened out now.
Thanks everyone for your advice and support!
I’m glad it worked out.
