I agree. Don't just back out and straight up ignore me when nothing happened to really warrant the silence, especially when we have to see one another daily and I am forced to toss and turn at night wondering what the hell to make of it and what, if anything, I should do about it. It's rude and very inconsiderate. Whatever the reason may be, there's no reason why the person who decided to just stop avoiding me out of nowhere can't be civil and talk to me at work. It's not like we were going out and had a fight or broke up something. This is why people become crazy cat people because the games other people unfairly play with others are just too much crap to put up with.
