[Age of Ignorance]

It's been a while now since my ex girlfriend and I were dating. We dated for 2 years. We broke up for the final time about a year and a half ago. A few months after, we reconnected and started sleeping together, but nothing came of it, and we stopped sleeping together about a month after we reconnected.

A year later, I want to reconnect. I don't know if I want to be on a deeper level with her, but I know that I would like her in my life in some capacity. She is my best friend's sister, and we get along like a house on fire when we're in the company of one another. She's just so easy to talk to, and great to hold a conversation with.

Obviously, I'm either lonely, or I still have feelings for her. I don't know which one precisely.

Should I try to reconnect? How would I go about doing it?
