How do you normally feel after the infatuation phase is over?

Is it normal/good to feel comfortable, happy, sexually attracted to the person even without the butterflies and nervousness? Or is that a bad thing because it’s becoming more of a friendship mode? I like spending time with my boyfriend and he makes me laugh but I don’t feel head over heels in love after 5 months because the butterflies have been gone for about 2 months now.
