Hello, I'm Moshaholic's girlfriend and we were just reading and commenting about your posts...
and i have a couple of thoughts i would like to share from a "girls" pont of view.
KEEP THE BIKE!...seriously. Unless it was a purchase that put you in the poor house, there is no need to sell it.
If you need to sleep in the couch for a couple of nights for her to get over it, do it.
And trust me, we do get over it.
You have the right to have your own things, and if this is what you want, then thats that. It is healthy to have your own hobbies and there for your own things.
This will always be the cause for argument because it is not always "whats mine is your"...
Maybe it does help us that we both like bikes, but if he decided to get something i didnt like, i would prob just deal with the fact that HE does.
Anyways....whatever your decision is, good luck.
