OMG, I feel your pain here! FI and I just argued about this last night, because I'm putting all my spare pennies away while he spent over $300 in the last FOUR DAYS on drinking with his buddies! He says "it's circumstantial" but whatever...pisses me off. At least he doesn't lie to me about it though...that's kinda sketchy if you ask me...I think you need to talk to him about that for sure. You guys need to be on the same page, even if you don't agree with some of each other's purchases. There shouldn't be any secrets.
