used to fall into this. I don't think it was, necessarily, any of that (for me at least).
It was just chasing the butterflies, more than anything (although some of it was, perhaps, just misunderstanding how love should feel).
When something is new it's exciting and that high you get from getting to know someone new is amazing and fun. Then, inevitably, something pops up and then it's not so fun anymore. It starts to feel a little like work. Not all the time...but sometimes. It's just not as exciting and, based on movies and whatnot, the perfect love is the one that always feels like that.

For me, I had to deal with a lot of stuff but I don't think the ones you listed were, really, what I had issues with.
I had impulse control issues, naivety about love, and I ignored red flags in favor of the fun.
