(M25/F22) foot obsession ?

My bf 25M told me he had fetish and I was like okay nothing crazy he just like feet. Then we moved in and I found out he has an obsession and was sending money for his obsession to other girls for pics, OF, etcHe said he wouldnt sent money anymore or talk to girls but his fetish will never go. I don’t mind the fetish I like it I do things sexually as well to try to satisfy him. The problem is not the fetish of the feet he like all feet he’s always going to be sexually aroused by other woman and look. I’m uncomfortable with that. If he just worshiped me I wouldn’t care but he said it’s all diffenrt woman feet is what he like. I told him I’m uncomfortable he said he will try to minimize it but idk if I should stay with him or not. ps we just moved in like two weeks ago so I’m just now finding out. What should i do. Do I settle and let him be sexually aroused by other women? Yes or No
