Most Helpful Guy
You always have a right to feel how you feel. They are your emotions. Now, did he do anything wrong? I don't know about that. It does sound a little like he might have misled you a bit maybe, but even that is kind of hard to say. He did seem to make a bit of a dick move to just stop talking to you, but that's not surprising from a young guy who might not know how to appropriately deal with the situation. (just takes the easy way out)
Regardless though, you don't have to ask anybody whether you have a right to feel how you feel. You do, period. I'm sorry things didn't work out for you this go around. I'm sure things will get better for you as things go on. Live and learn, right?
