How do you know when you finally get comfortable with your relationship?

Back story: My boyfriend and i have been together for almost 2 years, i used to be so uptight and was hella clingy, not gonna lie. Lately i’ve just been feeling more relaxed about not having to hear from him all the time and not having to be lovey-dovey all the time. We have cut down on having sex but we can just hang out in eachother presence and feel good. It’s a weird feeling but it’s a good feeling.
