Abuse, Love, Freedom

Start by saying, "We need to talk." Then, in a tactful, yet firm way, tell him/her how you feel. Has this person known that you have been unhappy with the relationship? How long? Don't stay with a person who makes you feel abused. Has there been domestic violence issues? I strongly urge you to call the Cops. That way, no-one else is victimised. The person needs to pay if physical abuse was involved. Then the person needs some serious help.

You already made the decision that the person has to go. But it's obvious you haven't talked to him/her yet. So I guess, whatever we will say here, that will never change what you already decided. If I am to step in your shoes, I guess I would have directly talked to her/him first about the problem before making the decision. Because with that preliminary talk, it would have been easier to tell her/him that "It did not work out so it is best that we proceed on what we have agreed before. We have to go our separate ways to find ourselves again." Since we can not bring back the time, the fairest thing to do is to tell him/her honestly that you want to move out of the relationship. Just pick-up the right place and the right timing/mood where and when you will tell the news.
