1. why does she want you to buy her the item in question? Why can't she buy it?
2. did you make her aware of the GAS acquisition months ahead of time to make sure she is cool with it?
3. you do not really "need" a GAS acquisition...it is called a "syndrome" because it is not dependent on necessity, it just happens for one reason or another. You need oxygen. You need food. You need work. If you have an amp, guitars and some pedals to make music, you are good to go; the rest is gravy.
All that said, it is important to have your lady to have an idea where your cash is going, especially if you have pooled finances. Because this is your bonus, you ideally have dibs on what to use it for...unless both of you have higher priority for the money like, say, a kitchen remodel or something. If she is still adamant, make her aware of how hard you've worked for the bonus but since you've already revealed that you got the money from being simply lazy..give her the money instead because if you ain't done anything to deserve the bonus, why should you reap the rewards for it?
