My observation is that, in general, in life, there is a very small percentage of people outside of your family who will love and accept you for you. ( And in many cases, many people don't even get that from their families, it's just more likely than from strangers) And if you are a guy, you have to, IMHO, accept that there is an even smaller percentage of most women out there who will love and accept you for you.
IMHO, a very small percentage of adult women will take the perspective of what will makes their guy happy or not. ( I'd say about 1 percent of all women) What makes them happy is mutually exclusive to what he can or cannot offer her in terms of social status or material items or external validation.
A much larger percentage, will base her feelings on how it makes her feel and what it can do or not do for her and whether it externally or internally validates her. (I'd say about 99 percent of all women) In these cases, how she might see your collection is relative to the rest of your life and what you have to offer her. If you are a powerful wealthy CEO and hung like a horse and hot women are chasing you all over town, then your collection is a way to "let off steam" or "a sign of your creativity" If you are not, and you are useful because she likes attention or is bored or wants someone to buy her a free dinner this weekend, then your collection could be seen as "embarrassing"
In your case, she was rude, but if you were, no offense, some super movie star like Ryan Gosling or whatever her cup of tea, had millions in the bank and was desirable to tons of women, do you think she would have said a word if she thought it was childish?
What I'm saying is whether or not a woman approves or your collection or not isn't always the greatest test to see if she's a good egg or not. A better test, IMHO, is simply to observe her when she is told "No" or doesn't get what she wants or is presented with a situation under some level of duress or faces disappointment to her raised expectations. Also observe her when she around people who can do something for her ( get her a job, help her get a promotion, access to certain social things, raise her social standing, etc) versus people who cannot. Look what happens when she doesn't get what she wants, how do you think she is going to treat you when you don't give her what she wants?
IMHO, do your best to try to observe people and make the connections on what their behaviors and reactions tell you about them as a person. And on your end, try to be the kind of person that you hope to deal with in life on a regular basis. Sadly, many people, I'd say most adults, live and die on external validation, which is why so many people are disposable to them. The only real answer to meeting better people is to try to be the best person you can be yourself.
Good luck.
