Walls are a thing not easily torn down or built. But it can be done. Most often it takes a lot of trust, and not everyone has the ability to trust at all. A bit of digression, but interesting. You say it's all because of you, of who? The operative question is who because to know the source of a problem is to begin fixing it. Put the past behind you and live without this person or fix the problem and reconcile. A decent piece, emotionally powerful if not a bit incoherent
