To be honest I realized even if he is into me my crabby ways are really getting in the way. Because I will say hello one moment and then the next time I see him I just flatout ignore him. As stated by another poster i do prefer being chased to doing the chasing, but I come off super aloof to guys who like me that I like in return.
Part of me wants to stay away because I suspect he is with her and the other part just wants to push through just in case I was reading the situation wrong. Like I said I have never seen them act romantically towards each other. But I have seen them be playful with one another. Because it is a proffessional environment they maybe just keeping things low. If not for the facebook page of the other co worker I would have dismissed any romantic relationship between them due to how they are towards each other.
Who knows, I am seldom sent to his department...so we really do not get to see each other as much.
