People can change, but don’t put your life on hold waiting for that to happen. I can’t say for sure what kind of person this is since I’ve never met the guy, but I can tell you that you will be waiting a long time if he is behaving how you described. Communication is incredibly important as a foundation for a relationship, and ghosting indicates they won’t be able to discuss things with you when things get really bad. This is a skill that is learned young and it is harder to learn it with age.

Let that flame die out and only let it be reignited if the person makes real effort to really talk to you.
