The guy I met on tinder has been lying about his job

I have been dating this guy that I met on tinder about 8 months ago. Things have been going really well. I like him, he likes me, I was surprised to find someone so decent. In the way beginning his profile said he worked in the oil fields, which I thought was super cool…he has kept up with this story for the past 8 months of us dating. Even so much as going away for weeks at a time “for work”. Today, I found out he actually worked at MCDONALDS and now I don’t know how to feel. I feel like I like him less due to his job…or maybe its because I found out he lied to me…idk…how do I even approach him about this? I don’t get why he would lie about it and keep up this whole lie.
