Suppose I just wanted to get it off my chest....it makes me feel an awful person and also really sad but I just don't like him - he's spoilt and demanding and rude and grumpy.
I would imagine I could cope with/tolerate/overlook all of those things (though often feel quite powerless as a step-parent to work at behaviour change) if I actually enjoyed his company but I rarely, if ever, get any pleasure out of being with him.
His behaviour/attitude doesn't endear me to him of course but the basic fact is that I just don't find him a charming or interesting child at all (he's 12 but i've felt like this for the 4 years I've known him really so it's not just an'approaching teenage-hood' thing.)
Sigh...
