Well, I just hit the send button. I thought long and hard over it, reassessed everything, examined the FB posts to check I wasn't going mad, thought over the wording, thought over what I wanted to convey/ say and it felt right. So, I typed it up, said a little prayer and hit the send button! Now it's gone, it's done and I feel relieved and a little bit eek!
Here is the final version - no real change from the previous.
Hi H,
I met with (my chairman) and your email really helped me and I got a lot of strength from your advice, thank you.
I got your recent email and I understand that you have moved into the flat and you are not there by yourself. That explains a lot about what has been going on between you and I since you moved out, and while I recognise that it is not the reason we are not together I can see that your efforts have been directed in another place.
However, I do realise it has been a year since you left so it is not surprising that you are moving forward with your life and it gives me a lot to think about. If I am honest with myself I am beginning to really enjoy the male attention that has been coming my way lately so I understand the attraction of a new relationship.
All that being said I understand there is a lot of stuff we need to do with the house. With regards to your offer of seeing estate agents, I am more than happy for you to go ahead and do that.
I am hoping that this clears the air between the two of us so that we can be more straightforward and comfortable with each other and that this doesn't mean that we can't see each other on occasion in a friendly context.
