Her reaction was destructive and a huge red flag for your future going bad. If you think about it, it seems she was just waiting for you to do something so she could go off on you.
Let's say next time you buy a magazine she doesn't like so she breaks your reading glasses (or, some comparable tit for tat exchange). This is a destructive relationship and you - you are foolishly allowing yourself to be punished for being who you are. You both need to knock off this kind of thing before someone gets shot, stabbed, or, burned...
If you are a masochist, maybe you're fine with that and it's well and good. But, you're not a masochist are you? You're a crossdresser. You both knew that and you both, for your own individual short-sighted reasons, made "rules" for PERSONAL behavior. But, in writing or not, you can't waive your rights to your PERSONAL thoughts and personal actions. If you have an itch, you have the unalienable right to scratch it - "contracts" don't apply.
As to relationships... She knew you crossdressed and she should know everyone slips up here and there in life. What you want is someone who works with you when you screw up, not someone who makes life worse for both of you.
Take your lumps and take your cue. This is not a good relationship for either of you.
Agree it's all your fault, apologize like crazy, and get out the door.
Maybe the next guy will like getting his stuff (car, stereo, dog) messed up more than you do. Or, maybe she'll figure out pouring gas on a fire is a bad idea.
Either way, this business of "living by the rules" is nuts.
Live better by loving one another well, not by "making" each other "toe that line" for the next forty years...
