An ex girl friend has come back into my life. After two months of seeing each other we have rekindled our love

Our first break up wasn't really a break up. We just drifted apart once we spent a small amount of time together we fell in love again. Last weekend we spent together in a hotel and really feel in love again. Next weekend we are going to S.F. All of this behind the back of her live in boyfriend. I was ok with the promissed break up and was just trying to keep things chill not going to deep, but that changed last weekend. We have both expressed love to each other. I know," if she did it to him she will do it to you " I can accept that as a posability and will know because she cannot lie to me. I can tell. So is it wrong of me to demand a time line and especially after last weekend that she at least no longer live under the same roof as him
