Boyfriends strange addiction...

So my boyfriend and I of 3 years recently just started getting in to the Adidas brand in Macy's. He's obsessed with the whole thing... the shirts with this pair of pants...etc. Ever since he found out I had a $800.00 credit limit he just loves to SHOP... of course he pays it all back back before the due date but sheesh.. I really only use the cards I have with my credit cards on occasion. And my parents did teach me the basics of credit, interest, etc. I have always been very responsible with my credit report and have not had any issues with anything late or anything. But is this a strange addiction or whaaaat?? lmao
