This was the message I started to write:
Dear (Husband),*
Where do I even begin? I have attempted to write things to you many, many times and I just concede that none of it can adequately express what I want to say.
I'm very torn, because I have this date tomorrow and I've started to get excited about that. The idea of something new, with a clean slate is appealing in its own way. But, and I'm not sure if it's a good thing or a bad thing, the slate will never really be clean because a marriage isn't just a previous relationship, and* a child isn't just a little quirk, he has a big impact on any future relationship too. At least, being the resident parent that is the case for me. Maybe not so for you.
So, although the date is exciting and fun, my preference would still be to work on our marriage and try to find a way to make that fun again too. Because I do still love you. I miss you and I miss our family. Because of those three things I think I could work on forgiveness. I'm not saying it would be easy. But I think it would be worth the hard work because I think we could get to a place where we would all appreciate the effort we had put in as the end result would be worth it. I'm also not saying that we say "sure, let's get back together, it's all lovely, there we go, all sorted". What I would like is to do is try going out on a "date" without the weight of what has happened hanging over us and just see if there is anything still left there.
That's as far as I got. I copied it to the notes on my phone rather than hitting send - see I've learnt from my earlier mistake!!
