You pretty much called the shots both times you ended it, possibly making her feel like she didn't have much say in what was going on. The best thing to do is let her make the choices this time. Tell her exactly what you want, and then for the love of soup--stick to it, or you will lose her on strike three. Ask what she wants, and tell her you respect her to have a say in where the relationship goes now. She gave you a second chance already and probably feels like she might get burned again. She's already agreeing to see you, and she's talking to you, so that's a great sign. Don't rush her, or make her feel like you're calling the shots once again. Make her feel special enough that she has a say also. Women like explanations, so if you tell her why it didn't work the first couple of times and you're reasons seem pretty valid, she will like to know that it's not her--it was just bad timing.
