Exactly my intentions. I still miss my ex, and it's still an effort to not look at her Facebook etc, but I'm enjoying texting this new girl. She's really nice. Maybe not quite what I want long term but we'll see.
Still gutted that my ex chose the excitement of a new relationship over a commitment to me. Like you say, she obviously doesn't know what she wants. It has really made me lose faith a bit though. Do we just fall in love with the person we spend most time with? That's what she did.
