Cherylbeth, this man is not going to marry you and you have made yourself dependent on him and this has hurt your self esteem and worth. You have to pick yourself up and move out now. Go back to a shelter and save up your money work two or three jobs and get back on your feet.
Never ever look for a man to save you, you must save yourself. Do not live with a man until he asks you to marry him, the statics for living together and then marrying are so low it rarely happens.
You need to love yourself, respect yourself and know that you have self worth; you are young and have your whole life ahead of you, so get out and make your life fantastic.
Stop feeling trapped and helpless, that you are not, you have two legs, two arms, eyes, ears, a heart that beats, a brain that works so use them!!!!!!
Be strong and believe in yourself that is all that anyone has in this world, you must love yourself first than you will find a wonderful man who will love you one day!
