The conversation I'm thinking of having with H goes like this:
"H I love you, have always loved you, and a small part of me will probably always love you. But I want to be in a relationship with someone who wants to share my life. I think that we want different things at this stage in our lives, and I understand that you are busy and are enjoying being single, and I support you in that decision. But it's not what I'm looking for. And seeing each other every few weeks isn't helping me. So I'd prefer it if you don't contact me. I cant imagine being divorced from you, I cant imagine it being the end of us. But I'm happy to sign the divorce papers if that's what you want. If you decide you want to have another go at having a real relationship with me where we share the good and bad times then call me. I want you to be happy, but I also need to look after myself, and I think its time for me to move on"
