Hello,
I've actually been in somewhat of the same spot, if I'm understanding your post correctly. I just recently had the break-up actually. When I was in it, I felt miserable because I was reacting so badly towards a person who had almost everything that I wanted and who cared for me genuinely, but whom I've had to let go because certain things didn't fit. I didn't feel right, and that feeling never went away, except for a few occasions when I thought they would go away, but the feelings of restlessness and the relationship being inadequate came right back the next morning. I'm not saying that a break-up is inevitable for you, but definitely working on yourself is key. I tried doing it while I was in the relationship, but there was so much mess being caused by us not being connected with each other that it was tearing us apart rather than bringing us together. But if your connection with each other is better, which I'm sure hoping that it is , and you can communicate things right, then perhaps this is a chance for you both to grow with each other. Hope that wasn't confusing and I hope that helps
