<human>: Give me a shortened version of the text

So I'm 17 years old and just ended my fifth relationship. This one lasted a little over a week and was with a girl I hardly knew, the one before it was about a month and I broke it off with a girl I had known for years. Before that the relationship was a little under a month, and before that the same. And so on and so forth.

This time it's because she felt I made a disrespectful joke (which I really did.) I feel like an ass but I can get over that, the humiliation in front of my peers will be harder but worst is that I really feel like I am completely unable to hold any sort of long term relationship.

I'm really not sure what to do, about the current breakup or anything after.
<bot>: I acted like a dick and got dumped and realized I have never been able to hold any sort of long term relationship.
