From reading this, it sounds that you are happy with your new guy and that he is giving you what you want most (open honest conversations that you could never have with your ex). It’s nice that your ex wants to make efforts, but his lack of communication is part of his personality and I doubt that will change. You guys love each other but don’t sound like a good personality fit. I think it’s important for you guys to clear up the break-up so you know where you stand with each other. It’s normal that it hurts as he is the one you were imagining spending your life with. But I think you are better off with your new guy who is understanding and gives you what you need.
