I think she could be the love of my life, we had a very heavy and fast relationship which I rushed and scared her off... she had some housing problems and ended up living with me for a while after about a 3month period of silence between us. She's been saying things like "im really under her skin" and "i've missed you" but I'm not sure if there is anything else there, I'm not sure if she's playing the I don't want to tell you no games or that she could be reconsidering the whole thing??
She has played games with me before but I don't know what else to do

Get away from her. She's using you until she solves her housing problems. Ask her to leave.
