Less interest..?

Started dating this guy four months ago, I am crazy about him so far. Never had someone treat me so good. I feel like he's crazy about me to but about 2 weeks ago he bought a motorcycle and that is all he thinks about. Worked a double today came to his house and all he wants to do is ride, I don't know if I'm being selfish by feeling this way? Help maybe I just need to be happy for him? Idk :(
