When you feel that you can not take it any more - it is time to leave. when you feel exausted, empty inside, when you feel that your life is going not the way you wanted...it is time to live. if you want to change your life..it is time to live. I was in relations for long time. There was love, but also were lots of issues we could not solve. I undertood that only love can't make relations to work. There are many more things that should be beween you in relations except of love. So i left. It was one of the best decision i made in my life. I met my husband in 1 year. In 1 year we got married and now i am happy. If you already have planned your life without this person in the future, it means you are ready to leave.
