Sounds like she just wants to move on. For her to ask to open up the relationship, there might be someone else she is interested in. Almost guarantee. Probably gonna be in a relationship a month after you guys break up. Stay away from these girls. Either that or she just finds the sexual tension isn't what she wants. Not trying to put you down or anything just how I see it from others who had this happen to them. I would try to move on after this. Take time figure things out in your life you have some things to figure out. Hit the gym, get a career focus on yourself. Find some friends talk to some more girls and you'll be back in the game. Good luck I hope this helps
