Happy couples (sorry, that's very grinchy isn't it)
Being told "you deserve better"
Not buying him things I know he would love
People feeling sorry for me

Not grinchy at all - happy couples and happy families although I have begun to realise things aren't always as they seem!

I often completely forget that we're not together and have picked things up to buy for him... even my online shop has a 'have you forgotten' section - all filled with his stuff - beer, male toiletries, etc. 

I hate that look people give you, with their head often tilted to one side, "Ahh that's a shame"... Grrrr

Shutting the front door in the afternoon and knowing no one else will be coming through it

I hate that people think mid life crisis is a joke.

I hate that  empty spot on his side of the bed
