Hang on a sec - this can work the other way with regard to jealous partners, and those who think that they should spend every waking moment together.
I've been in relationships before, where after around a few months, i'm getting hassle from her, to pack in the D.J'ing. One especially nasty creature even asked me to choose between her or D.J'ing

- Guess which won!

.
I think for a relationship to work, both parties have to realise that there will be days when each person is out following hobbies, persuits etc on their own, and that being joined at the hip is not a good onus for the future. She may persue flower arranging, Evening Classes, Line Dancing, D.J'ing or whatever, He could be Fishing, Playing Pool, Watching a Football match or D.J'ing. If your partner wants to join you in these activities - great - if not then they shouldn't expect them to simply give it up.
I know a few D.J's who have been forced to give up D.J'ing and all of their hobbies / pastimes simply because the "other half" told them so!. Sadly most of these relatonships / marriages broke down in the years following. I think Karen and Kev are correct - you can spend TOO MUCH time D.J'ing and away from a partner or spouse and so a break for qualiity time together is in order. However, if your only out on the occasional weekend or now and again, then it wouldn't be fair to expect you to quit altogether.
Am I starting to sound like Claire Raynor yet??
