I will mention what I said on another thread. That if a relationship reaches the stage where a partner asks you to choose between them and something that you enjoy doing then perhaps its time to move on, since IMHO that relationship is doomed from the start otherwise by the time your married you wont be allowed to leave the house.
Let's face it, for most Part Time D.J's - working is limited to the Weekends, that leaves, Sunday, Monday, Tuesday, Wednesday and Thursday to cuddle up on the couch and watch TV!

. If that isn't enough then your gonna get sick of the sight of each other - accept the D.J'ing as an escape and a blessing for both of you!.
Everybody needs time to follow their own hobbies, interests and pursuits, if a partner wants to join you to D.J then great, if not then perhaps they should arrange to get a hobby themselves, or just accept that every now and again that your not both joined at the hip
