Hi. I split this post from the original thread because I felt that it deserved to be in a thread of its own, so that you would receive more support because people would see it.
I'm so sorry to hear that you're going through this abuse, and being denied financial independence. By doing this to you, he's exerting a lot of control over you, leaving you financially dependant upon him. In effect you're working for nothing, and providing him with extra income. He's also jeopardised your chances at college. Is there anyone at college, ie a tutor or welfare worker who you could approach, and explain the situation to? They might also be able to point you in the direction of domestic abuse agencies who could offer support.
He is relying on you keeping this a secret, and if you tell someone, he will have less power over you. The more support you can get, the less isolated you will be. Would your family help if you told them? You will need to be very careful, however, as the time when a partner leaves an abusive relationship is often the time when the person is in the most danger. Please bear in mind that this could potentially escalate into physical abuse. If you choose to leave, you will need to plan this carefully.
This link will give you advice on how to leave an abusive relationship before it escalates into physical abuse.
domestic-abuse/topic11734.htmlOnly you can decide whether to remain in this situation or to leave. At the moment you have no quality of life, and this is not likely to improve. He may appear to change if he thinks you will leave him, but the abuse is likely to continue again, and he has proven that he is capable of great cruelty towards you.
You may qualify for Legal Aid. A good lawyer can advise you about the mortgage etc, and it may be possible for the courts to force him to contribute. Some Domestic Abuse agencies also have access to legal advice.
Speaking to a therapist can help you rebuild your self esteem, and to take on board the fact that it is not your fault. This may be something you might want to consider at some point in the future.
I have PM'd you details of some Domestic Violence Agenices.
