Is it possible to live life being constantly busy?

I am in a pretty bad mental situation right now. I am married but the not happy with the marriage and my partner. I constantly feel empty and lonely. Specially in the evenings when I have free time, my mind constantly makes me feel very lonely and irritated to seek out connections with people. I also daydream a lot about what it could be with other people. Unfortunately, separating from my partner is nearly impossible. The only thing I can do is to be busy with something. Watching Netflix, doing some other works, being busy till it's time to sleep and then repeat. Can I live like this forever?
