I need help

I'm not sure what to do. I've been (best) friends with this person since 2017, and now I don't know. They gotten married recently and it feels like we spend less time together. I have suggested I could come over or we could watch a movie like old times, but I'm not sure. It feels like they don't really out an effort into talking to me, hanging out, or checking in on me. They have told me recently and in the past they tune me out when I'm talking. And even told me they needed to drink more if they had to listen to me. Which really hurt me.

I feel like shouldn't be their friend anymore but I don't know how to end the relationship. I feel like if I stopped talking to them they wouldn't make an effort to reach back out which had happened for almost 5-6 months. Until I reached out to them again.

At this point I think I'm going to just stop talking to them and slowly drift away. Which is hard since we've been friends for a long time. But I don't think the effort is put back, even before they gotten married.
