Dear...
You are a hypocritical, snivelling .
Not only were you 'economical with the truth' about the amount of contact you have with your poor ex, but it transpires that your caring role ended purely because you stopped being paid for it. Not just by HM Government, but by her. And the only reason you are hanging on in there now is because you hope to collect on her life insurance when the brain tumour finally kills her. I know she keeps threatening to cut you out of her will and, actually, I hope she does.
Hanging on in there, even though you really wouldn't like it if your current partner was in a similar situation. Hanging on in there, but proclaiming yourself to be single - like you did when we were notionally still together. You announced to the world that you were single almost a fortnight before you announced it to me! What a hero!
I'm glad I spotted the fact that you wanted to glom onto the social life that I've painstakingly built up in the two years I've been in a strange town, and didn't introduce you to too many people. You are too lazy to do this for yourself - despite the fact that you've lived in this town all your life - because the best way to meet people round here (as I discovered by accident) is to involve yourself in community projects.
I'm glad I hid the fact that, despite having had two very lean months when we were together, I'm not badly off financially. I did notice your remark 'Y'know, if I'd realised you were that skint - I wouldn't have bothered!' But then, given your total lack of scruples re your ex, and the 'Bank of Mum and Dad', I'm not really surprised. It would have been nice if you'd gained a bit more self-reliance by the age of 50.
And now you're advertising yourself as having 'been single too long'... I'm sure you'll continue to proclaim yourself a 'Nice Guy', whilst having no concept of passive aggression. I'm aware that your obstructiveness in returning the last of my belongings from your flat, and denying that you'll be around later when I could just come and collect, is part of your general modus operandi and nothing to do with me.
I'm also aware that the searing rage that I'm feeling is par for the course, too, and I'm just using it to energise myself in other areas.
And I'm sure that I'm not the only person who could cheerfully flatten you.
