Shopping for makeup is my favorite. All the different colors and textures and ways to change your look, just by using different makeup products! But there are obstacles to my desire to possess all of these makeup products, namely, my hubby. Oftentimes, he is shocked at how much money I can dish out on makeup, and he complains all the time. I'm sure if you have a lover who shares a bank account with you, you also run into this problem.
Well, we have worked out a little system, and I will suggest the same for you if you are dealing with the same situation: an allowance. An allowance? But Geneys, that's for little kids, that's so junior high! In reality, though, this is what it takes for me to keep my spending in line. Trust me, if I had a zillion dollars, I would walk into a MAC store and just buy the whole freaking place--my hubby has to send my sister with me to go shopping there so she can keep an eye on my wallet.
So my solution to your problem is just basically, make a compromise with your lover. Decide on a number that you will allot for this kind of spending each month, and try your very best to stick to this number. In our world of credit cards and spending based on debt, I think this is the safest way to make sure you don't dig yourself into a hole from which you cannot get out. Plus, you will make your lover feel happy and secure.
Below is a picture of my hubby and me from right before our wedding. My hubby looks exactly the same now and I have fattened up like a cow in a cage, which actually, is literally the situation right now--I am stuck sitting at home all alone with no job or kids, with nothing to do but play with but my makeup. Just believe you me, I spared you a look at myself right now, LOL. But look at his handsome face, why would I want to break his heart by spending all his money? I'm sure you feel the same way about your lover, so make a budget and buy in moderation.
