Should I Leave?

I have been dating my boyfriend for 3 yrs. We met in a thriving metro city, and he really wanted to move back to his hometown (small rural town). Now don't get me wrong, I'm originally from a small town on Lake Erie (more industrial than rural), but I never wanted to move back to Small Town Life. Because I love him, I did make that move a yr. ago, with his promise of getting engaged shortly after. Due to the economy (uh jobs in a small town during a recession are next to none) and my car breaking down, he has been unable to up & buy a ring. He hasn't put one on layaway, no in-store credit card, nada. I have now been here, in a town where I still have no friends or social life, for 15 months. I already fell in love with him when he told me that he cannot enjoy sex (!) because of a broken spine he had incorrectly repaired in high school. He feels numb sensations and causes him "mental issues" when we do have sex. I love him and have been very patient regarding this because of how wonderful he is, or was.

He has a wonderful family close by who cannot wait to help out with any future children. He has been the bread winner and supported during my transition. Although, before w moved I told him not to be "a bachelor" and take allll winter off again (his work is groundskeeping/landscaping/greenhouse). He straight bummed around all winter while I worked a very horrible physically dangerous job w/ juvenile delinquents (only FT work here I could fine). Now he works 10-13 hour days, 6 days a week, and offers no sort of help regarding the chores. I feel like we are roommates now, as he picks and chooses when to get physical with me. He plays Xbox and sits around watching tv, while I want to go out and spend QT with him.....it's been 3 years. Should I leave before there even is a ring?
