It actually sounds to me like a very normal phase in a relationship. My husband and I have been together 14 years. Not all of those years have been perfect. I guarantee you there were points we both thought: this isn't how our life was supposed to be. The good news is that things go back up again, the hard parts don't last forever. I would advise you to keep talking about your feelings together. Never stop talking. Each of you give the best you have to give. Remember how much you love each other and this phase too shall pass.
