I just got the following email from him. Pls help me interpret!!! What do I do with this?

Hi. I just wanted to say hello and that I was thinking about you. I care very much about you, Zimmy. I continue to learn new things about myself and our relationship. There is so much I wish I would have done differently over the last 7years. I know how much you did for us and for me during that time. I wish I would have done more for you. I wish I would have made you my priority like you made me yours. I wish I had communicated better. I wish I would have recognized and appreciated your dedication and commitment....and everything you did for our relationship. I wish I would have reciprocated that back to you. You deserved it all and more. I see you now better than ever. Wherever life leads, I am determined to be a better person.

I know I have caused an unimaginable amount of pain. That burns my heart every day. Please forgive me for writing this email. I know your wishes. I know you want / need some time to yourself. I respect that completely. I'll leave it at.

You know I love you,
C
