<human>: This past weekend I recently was contacted by my ex gf of over 3 years after we broke up and went 2 years without speaking. She apologized to me mentioning how she never gave me the credit I deserved because I was such a good guy to her and she never fully appreciated it then. She also asked to meet the next time we will be in the same city. In which I agreed.

The texts I was receiving initially caught me off guard, I was out sober cabbing my friends at the bar and phone starts buzzing. With a number I vaguely remember but was not saved in my contacts. I asked who was texting me and she responded with her name. I kept the whole conversation generally light hearted. She apologized with a pretty long winded text, outlining some things and mentioning that she thinks about me a lot. 

The conversation stayed pretty light. We talked about our dog we have together and I sent her some pictures of our dog. I know that she has been in a relationship but I never asked if she was still with him. Her friends had came up to me last year and mentioned that they hated her new bf and wished I would try to call her again. I didn't. 

That was Saturday night and I haven't gone out of my way to start a conversation with her. Although, I feel like I should have my guard up since our break-up left me pretty devastated as we were starting to make plans for our future when it happened. I guess what I'm asking for is advice on this current situation. Whether or not it's something I should try to pursue or try to rekindle a friendship with her.

Provide a brief overview of the text.
