“My manager is being really weird”

I don’t know what to think of my manager. We communicate work issues through texting. He has ranted about his boss and called her names. He has also said things about other people. He calls me madame and sunshine and never uses my name, but does this with no one else.

He also has sent a hug emoticon once. The weird one that is blushing with hands. I don’t think he likes me, but the situation is weird. What is he doing?
