Does she like me? or is she playing me?

Pretty clear to me that she is wanting her cake and eat it too...and she is in effect cheating on you...you need to put a stop to that...you need to tell her straight out...if you do this again..dont' come back ever..either we are going to build a solid relationship with trust, respect and love or we are going to part ways so I can find that person who does want that solid relationship... We are getting to an age where we need to a bit more mature and cut the dramas out of our lives ...if we are gonna be happy....we need to commit to working at it...and not taking breaks from it...So what is it going to be...I need to know straight up that you are in this with me for the long haul...
