How can I continue this affair and not cause friction within the family? I want to leave my husband?

You need to take things one at a time. First look over this site on self esteem and relationships. Then, try to sit down and see if you and Amanda could afford a place of your own and since Randy beats his wife, she may want to get into into that also or you could all move in with her perhaps. You need some time by yourself with no men involved because leaving a bad situation another man may seem appealing now but when you finish school and raise your self esteem you may find someone better for you and the same really goes for Amanda when she finishes college. Give this site to Jill and she may get some help from it as well. You three girls are thinking of yourselves as white trash but you need to rise above that and this site may help you. Remember the girl who went from sleeping in trash cans in alleys to a law degree from Harvard and success, and realize that you can do as well. It just takes work and self esteem.
