I'm a single guy and I love the job. First year pay wasn't great, but I still managed to buy drinks for my friends on my days off.
I commute, and being single in this category is huge. Not having to worry about disappointing somebody by not making a flight is a huge advantage. On my days off if I don't feel like going home, I just hop a flight to go visit any of my favorite relatives or buddies from college and high school. Your roll-a-board will become like a your mobile home.
Flying airplanes for a living is awesome. Sitting in hotel rooms is actually a good way to rewind after traveling, partying or doing chores on your days off. I enjoy never having to make your bed, clean dishes and not paying for utilities. I bring my computer, watch movies, read all the books I wanted to in college but was too busy studying/drinking/recovering and catch up on my sleep.
Having good work rules does wonders for QOL and pay. I'm on second year FO pay and basically my pay breaks down to: 50K for day work weeks, 40K for 4 days and 30K for 3 day work weeks.
From a single guys perspective I definitely endorse the job. Good luck
