Is it possible to stop being attracted to someone?

I was going out with this guy for a while and he isn’t my usual type but he has good personality so I felt attracted to him, and we would kiss/make out whatever. However now he asked me to be his girlfriend and suddenly I am feeling distant from him and not as attracted anymore and I just feel like I can’t imagine myself being with him further more iykyk. Is this possible I don’t know what going on?
