I'm jealous of my fiance for buying a switch
Why are you jealous of your fiance for buying a switch console?
Because he doesn't even try to win me over or anything, all he does is game.
You shouldn't allow yourself to get caught up in trivial jealousies because they will bring down your relationship to a lower level. Sit down and talk out your feelings with your fiance.
It isn't just the jealousy. The worst thing is that he bought it with our joint account money.
If you share a bank account you need to communicate with each other about how to best use your money together. Couples therapy might be able to help you open up new communication channels with each other.
