...Yup, this sounds healthy.
Just to clarify here...you want to to subjugate your girlfriend via an album of magical mind-control music that will compel her to stay with you forevermore by assaulting her with the unearned guilt of a transgression she has not actually committed in what I assume you feel is a subtle means of coercing her into being an obedient prisoner in a union you're not even serious about?
I mean disregarding for a moment the horrid misogyny at play here, I'm going to question why you would go through all this effort — you state early on in your wall of text that if she breaks up with you for this little experiment then you don't care...so then this whole venture is nothing but a power trip...perpetrated against a person you ostensibly care for?
Respectfully, I don't think "we" need cover art, a title, or anything to do with this CD. I think you may want to examine your idea of a healthy relationship though.
This is not a good way to emerge from depression.
