I feel so bad

My dog had left our family two weeks before.But I just knew it this morning.I am really surprised at this news,and it's too bad to me.Although it only stayed in my family for half year.But it was the first and only dog I like.I know that I will never love anyone else.I just want it back to me.But I know it's impossible.My father had told me before that you have to give up something in your life,in order to accomplish other things.My character is as headstrong as my love.When I met the first man I love,I will not love other men.Sometimes it's good,but sometimes it will bring me more troubles.So I often feel a little tired,because I could not stop my loving to the things what gave me good effects the first time.Now I must find a way to forget the lovely dog.
