If your conscience bothers you about the multiple guitars, sign onto my favorite hangout, the flatpick list. It's a great support group - although no effort is made to cure, or even control the problem. Only cure the guilt.I have no problems with my significant other about multiple guitars because (a) she has fiddles like I have guitars, and (b) we agree that gig money is for toys and day job money is for necessities. But you can always find a weakness to attack. Many guys with several guitars have wives who spend more on clothes. Or you can simply point out that you don't use drugs or drink or smoke much (unless you do, that is).
But maybe I ought not to go into the marriage counseling business.
