She would say she was on her way, then not, screwed up my plans one night. It kinda ticked me off. She said she was going to call at 4 yesterday. I went out of the office, she didn't call. Then I texted her "How many times you going to blow me off this week?" She texted back "I'm sorry. I was on the phone with my doctor."
Without more historical details, I can't draw much of my own opinionated conclusion and I readily admit that I can be totally wrong, but here goes...
Background, currently in a 7-year relationship, been in a couple 2-3 year relationships, dated/laid enough (too many probably) women, had one love I'd say was true love...
Depending on the assumed age of the relationship and the frequency of these events, I simply think you overreacted. I assume this is less than a couple months based on the other thread about first date tips, and I assume this happened a couple times and not every day for weeks.
Dating should progress as both parties see comfortable. The seriousness, found in the frequency of togetherness and the instances of communication, should be laxed. The relationship, found in how those involved feel during periods of seperation and how expectations are shared, should be stress free.
Either you were looking for a conflict, or you were ready for a more serious relationship than she was. Either way, it was not at that point the right path for one or both of you to be walking together.
If she desires a more hands-off approach to a new relationship, and you're an all-in kind of guy, it just won't progress because the seed of conflict will always be there. As soon as one of you waters it with enough doubt, it will rear its ugly head, which seems the case.
My closing thought, people don't change. They simply discover or choose to reveal who they truly are. Everyone needs to find their complement. Mathematically speaking of angles, the sum of two complementary people equals the right couple.
But, what the hell do I know. When it comes to matters of love, I'll admit I'm a total hypocrite.
