I am sorry you are going through all this. I think it is really common and sad that women tend to lose themselves in relationships too often. I too lost a lot of who I was in my relationship and it has been a long road back to finding me again. I agree with the counseling idea whole heartedly, therapy has been a heaven sent answer for me. I needed to regain my independence and my self esteem, and counslers can really help you gain perspective and healing.
Love is a funny thing, it changes over the years, I am in no way suggesting you go back and try again- that is all you... but make sure your perspective on what love is and how it feels is healthy. We may not have that exciting love that was there in the beginning of a relationship forever- we change, our relationship changes and our lives change so of course love is going to change... if you decide to give your relationship another try then both of you would have to commit to bringing love and intimacy back to the realtionship. (Intimacy not being sex necessarily but closeness and really getting to know each other.)
I hope you can find the answers and support you are looking for... I would whole heartedly suggest getting a therapist who can help you rediscover yourself and possibly your relationship. You deserve to be happy. Good luck
