Hmm. But silly arguments shouldn't trigger a run, or any drastic action from a partner. Silly arguments should pass as quickly as a fart (sorry to be crass but that's the only thing that popped in my brain). She sounds like she needs to be chased i.e. high maintenance, whereas you are more low maintenance, i.e. your nonchalant nature. Maybe underneath it all, you two are incompatible as far as your relationship styles go? Sure, opposites attract. But similar natures tend to have a more hassle free time together in a relationship.

She sounds like she's making convenient excuses not to reconcile. Maybe she likes the back and forth, push and pull now that you are broken up, because she thrives off of that kind of drama. Ugh. If she really wanted to reconcile, nothing, and I mean, NOTHING would get in the way of that. When two people want to reconcile, they just...do.

It's disappointing that you're in this situation with this woman, because obviously you two were once very happy together. Hopefully, she'll either come around and stop making excuses and reconcile. Or, you grieve, move on, and hopefully a more compatible woman crosses your path who will not make excuses or run at the slightest silly argument that happens when you are in a relationship with someone.

I really hope it works out for you. Everyone deserves to be happy.
