Who am I?

I feel that I am losing myself day after day.
Since we were together, I was only to find that I was living for Ou. At that time, I held that I would be with you till death. While now, I am not sure.
From the small things in daily life, we both find that we have many different things between us. When I said or did something, you always refuted me. And when I asked about your idea, you would say that I should have my own judgement. Maybe I was wrong. In my mind, I think that this is the respection I give you. Now I think I shall change somethings to be myself.
In my deep heart, the reason you don't pay much attention to me is that you are not sure whether you love me or not. I sincerely hope that day will come early. And then we will live together with full heart, till the end of our lives.
