Unhappy relationship?

I’ve been fighting with my boyfriend nonstop. It’s been going on for a while. I won’t get into the details because it’s complicated and difficult.

My question to you is..have you ever been in an unhappy relationship and fixed it? We’ve been together for such a long time. He’s always been the one for me and we’ve been planning our lives together. He’s like my missing puzzle piece, but I believe I’m unhappy with our relationship and don’t know what to do.

I just want to know if others have been in the same spot and how to deal with it. Or if you’ve been in a rough patch in your relationship, how bad was it? Did you fix it? If so, how?😔
