I can't relate!
I have quite a few basses. If I have two similar ones I do something to make them sound or feel different- fit mutes, or flatwound strings.
I like swapping between neck widths and profiles, string spacings, 4 and 5 strings, headless and normal, cheap and not so cheap, passive and active, light and not so light, aggressive and mellow.
Currently getting a huge kick out of my £70 Harley Benton kit bass with a Squier neck. Very light and sounds HUGE! Before that it was my Sire P10 getting all the attention, totally different bass!
So no I don't fall outof love with basses, I'm polyamorous with them!
