When is it okay to date okay?

I recently broke up with my boyfriend, we were together for over a year.

A friend I went to school with recently started talking again, and you can truthfully feel the tension between us. We’ve always felt this connection, like we could be ourselves with each other. We make each other days, and haven’t went a single day in probably two weekend not talking to each other.

We’ve started talking about if either of us catches feelings what we would do.

& I don’t know. Maybe I’m over thinking this. But I feel like something could possibly happen.
