A Potential Regret

I've been entertaining thoughts about a rendezvous with Sara. But only letting myself think about it when I'm doing good. Obviously if I'm longing for her my judgement is going to be clouded. I'm just thinking about regrets and how I'll feel if I never try to see her again. She's good at shutting down emotionally after our hookups, so I'm not too concerned about knocking her back a ways. And gawd knows I know she needs the release as much as I do. My biggest concern is having to call her. After the incident with her personal email account, I don't want to force her into changing her home number as well in order to totally shut me out of her life. And I'm also wondering if its better to give her short notice - meet up within a couple days - or long notice to give her something to prepare and look forward too. Obviously one way gives her little time to chicken out, but the other way keeps her from panicking. V-day is coming up real soon so I need to decide.
