babysitting while my bf is in town

kinda mix of AITA but..

my bf is in town for valentines day and i got asked to babysit for my now pretty regular babysitting family for three hours friday night.

i cherish eveytime we see each bc we are long distance and completely clear my schedule, but we don’t have have anything particularly planned besides our dinner on vday and i can tell im being asked to babysit so that the parents can go on a vday dinner.

the reason why im thinking about it is that i will get 60$ that we can put towards our weekend together. has anyone ever had a similar dilemma? should i babysit or naw. been babysitting them since november
