I know the proper use of the word is with “with”, although I can’t seem to find any evidence to support it. I rarely hear it used this way. Am I wrong?
From the American Heritage Dictionary:
***Usage Note: ***In the sense of “attraction,” affinity may be followed by of, between, or with. Thus one may speak of the close affinity of James and Samuel, or of the affinity between James and Samuel, or of James’s affinity with Samuel. In its chemical use affinity is generally followed by for: a dye with an affinity for synthetic fabrics. ·One might want to avoid using affinity as a simple synonym for liking since 62 percent of the Usage Panel rejects the example Her affinity for living in California led her to reject a chance to return to New York. Nevertheless, the more sophisticated tone inherent in this use of the word can lend an archness to certain contexts, as when Barbara Tuchman writes of Kaiser Wilhelm’s “affinity for coarse physical jokes practiced upon his courtiers.” This may be why 65 percent of the Usage Panel approved of this quotation when it was presented as an example.
Excellent, thank you.

Doesn’t mean that the minority opinion isn’t valid.
I’ve never heard anyone say “affinity with.” But I have heard ‘affinity for.’
Interesting

in the US, most people say ‘if I was’…doesn’t mean it’s correct

If I was to say to you
Girl, we couldn’t get much higher
Maybe the “if I was” was Robbie Krieger’s doing, as will all know Jim would never have made that mistake.
