We own a car, an HDTV, and two cats and a dog together, and are renting to own our current residence (--a good deal, actually). If I leave my girlfriend--which I will probably do eventually, regardless of what happens with my co-worker--I will let her have all of this stuff.
What makes you think leaving her will be easier or a better idea eventually? What advantage do you gain by putting off the inevitable? Is it just laziness? Are things comfortable? Inertia?
I'm not trying to be an ass. What I will say is that it will not get any easier, and you gain nothing by putting it off.
My wife of 6 years (together 10) and I just separated recently. It was not easy when it was decided, and I'm sure it would've been much, much easier if we had decided to split before we got married.
The material items between us were not an issue. Splitting our three cats and dog up was the most difficult, but we came to an arrangement that works well for all. I now don't have a car, a TV, most kitchen utensils, etc... it's not a big deal, and I'm not worried about their loss - at all. The material items are cursory, and whether you are to be generous or not, it should not drive your ultimate decision. It is only an excuse.
Find your balls right now and end it. If not for yourself, do it so that she is free to live her life, fuck other people, etc...
