Porscha - I agree with Penny - this woman may have a crush on you. You say she rubs you a lot - perhaps she is just able to this with you and not with her spouse. Some men can be cold clams.
If you're able to hold a conversation -I'd ask her what she expects from you, in this friendship.
Could be she's shopping for a new partner.
Check out the husband - make sure he isn't a policeman, soldier, sumo-wrestler, prize fighter or insanely jealous of anyone who is friendly with his wife.
