Well, I tried to have that heart to heart with him last night but he wasn't having any of that. So I walked away to give him a cooling off period and will try again today when I get home from work.
I explained to him how the cheap weights I have now are crap and how they scratch and fall apart and what not and he now understands why I want something better. I also told him that I am an adult, and when I want something, it's not just because 'I WANT IT!!' I do research, and make sure it's really what I want and when I finally decide it's the best item for what I need, I don't need him second guessing me just because it might be a bit spendy. So we made a little progress.
I just wanna add that I'm not completely innocent in this either. I HATE to clean and I've developed a few bad habits like not throwing away trash and letting the dishes go for too long. And when the mess starts to bother him, he will clean it up. He has told me he gets frustrated because he feels like he is the only one that is cleaning. So I do need to suck it up and start cleaning on a more regular basis and work on MAINTAINING a clean house once it gets there. But you are all right, the condition of the house should not matter when I want to buy something.
Thank you all for your advice and encouragement. Reading from you ladies empowers me to stand up for myself! I'll let you know how the second talk goes!
