you've assumed a couple things wrong. 1/my girlfriend doesn't mind waiting around for me to take shots and she's extremely encouraging about me taking over the laundry room and turning it into a darkroom and having all kinds of photographic shit lying around with no complaints. 2/she only tells me to condense my equipment, 'cause i bitch about having too much. 3/she's too awesome to "trade in"...also, trading in would assume that someone else is willing to date me.You have the wrong girlfriend.
Mine encourages me to take what equipment I want. Encourages me to take photographs and never complains about waiting. And if I decide not to take camera equipment thats ok too.
Time to trade in your girlfriend for a newer model.
