four MONTHS? all this hoohaw transpired in four itty bitty months? you moved her in, paid for everything, she's bounced around rehab, her folks, a recovery house, your place and all the while binging her guts out??? you really want all that back?
i'd ask myself WHY. you can't buy love and affection. doing everything for someone else won't get you anything but broke and disappointed. she's right, she does need to focus on her recovery 100% and i hope she does......but so do you.
