AITA - for working during my GFs tryouts?

AITA - I (26M) work as a HVAC technician. I have been working a lot recently to make ends meet but recently have been doing good for myself. I make pretty solid money ($31/hr) and have been able to save up a lot of money for important things like rent and car payments. My gf (18F) plays soccer and had a big varsity try out coming up. I was going to attend the end of the try out but got an offer from my boss (66F) to work extra for $52/hr on a project. That’s nearly double what I make, but I had to miss my gfs tryout. She made varsity, but is clearly upset with me and idk what to do? AITA for working for a little more money for ends meet?

Edit - post got removed idk why?
