<human>: Can you condense the text into three sentences or less?

I can remember from my first relationship at 17, and even then my relationships would go the same way. The process would go a little something like this: I fall for a guy, we date, we enjoy the relationship for while, and everything's great. Some weeks pass and at some point, I feel so disconnected from that person, and that we shouldn't be together anymore. I break up with him as a result.

This continued on like that through my high school years thinking it was normal, along with my freshman year of college until one of my friends pointed out how I couldn't stick to a relationship for more than a few months and asked if I had commitment issues. I don't think I have commitment issues, but if my case isn't having commitment issues, then why am I so bad at keeping the attraction going in a relationship? All of my feelings for someone can drop the next day I wake up and I don't know how I'd even address that to someone without seeming like a cold-hearted ass.
<bot>: My feelings for an SO can drop in an instant and I don't know why. I just feel like all of the affection I had for a guy is just gone.
