<human>: Can you summarize the given text in a few sentences?

I've liked this guy for about 5 years now, we'll call him Mark, we're both 20 so this was when we were still in high school up until this point. It's been on and off communicating with him but the feelings I have for Mark haven't gone away. I've told him how I feel and our feelings are mutual towards each other but the timing was always off. As an individual I'm very introverted but with Mark I am more open than I am with others.

He had a girlfriend for a year and a half and just recently in the last month they broke up, so during that year and a half I was very friendzoned. I don't know how or when he will be ready to commit to someone again, but I do have plenty of patience. We text on a regular basis since they broke up and his texts seem suggestive but I don't want to be a rebound.
<bot>: A guy who has mutual feelings for me just broke up with his girlfriend and I have no idea how to pursue a relationship.
