Falling apart

I feel like my relationship is falling apart. We never kiss or cuddle anymore. I don’t really even have the desire to. We aren’t communicating well. We fight a lot. Is this just a bad spot? I’m I depressed? Will it get better? I just need advice and support because I have no one to talk to. From the outside everyone things we are the perfect couple. I am afraid to tell my friends what’s actually going on
