Questions: Relationships

So here's the situation, basically this girl and I started talking platonically online. We're both pretty bad texters. We spoke for about a year until we met in person. We had two fantastic dates where she expressed desire to have a relationship with me.

In the time since those dates, she told me that she doesn't want a long distance relationship but has said she wants us to contact each other if we are ever in each other's area. The communication has totally died to the point that she doesn't respond to my incredibly occasional texts. I recently graduated from law school and she couldn't even be bothered to send me a congratulations text when I told her.

There's bad communication and then there's this... this is just pathetic and insulting.

Part of me wants to call her out on this and ask if she wants me to stop texting entirely, the other part thinks I should just assume she wants me to piss off and just let things go.
