No, don't rant, be calm and collected, be
nice about it, use a soft tone. Just try this one, if you tell her that you don't want to sell it, and she gives you some garbage, like do you love it more than you love me? Say this do you want it gone more than you want me around? Just leave it at that, don't give her an answer, just see what she says, and if her answer is yes, then ditch her. You can be happy for an hour with bedroom play, but be miserable for the rest of your life, because you no longer have a say, because she's holding your chain, and it won't be
your life anymore, it'll be hers. Not worth it if you ask me. Oh and if you think this kind of attitude will leave you single, it won't trust me

I am married after all. Did you ever see School of Rock? Everyone who has probably just thought the same thing as they read that (the guys girlfriend in the movie walked all over him all the time, and he had no life thanks to her).
