I've been thinking about it. It seems that it comes closely on the heels of redoing her bedroom, redefining who she is, as it were.
It's easy for me to say, out here in cyber land, not paying your bills or looking at a future D, but I would be in inclined to go with it. Go with her. Be excited that she found something she liked! I'm feeling it has something to do with HER inside, not just a car.
Yes, it's a gamble. You may lose. You have to ask yourself if you are on the other side of this thing -- D or reconciled -- can you live with your decision.
Pre-MLC my H used to say "it's just money".
But we did go through a lot of it in MLC. Seems to always include cars, Doesn't it?
I did say "no" to my H last December when he wanted to take and use our SUV and it was already in my name only.
But we were in a different situation than you are in.
Just thinking back, if you feel you can afford to lose some, or won't feel jealous if things don't go your way (like her taking the new car dancing with men, etc) I am all for getting the car. And using it as a way to applaud her new identity.
