Wow. Throwing a drink on someone is assault and you could be arrested for that. Your reaction was completely over the top and uncalled for. If you are in a healthy, trusting relationship, that hug shouldn't have struck a nerve. There is obviously a lot going on besides the hug...trust issues or insecurity or something.
I completely disagree. I would have done the same thing. I don't care if my husband hugs his female hugs, but a hug as intimate as that? That should not happen.
