Hi Clueless - I'm kind of new to this, but have been through some of the same situations. My H also declared his undying love for me on Facebook and then got involved with someone he went to HS with - also through Facebook! He changes a lot when I see him. Sometimes he is teary and open and seems genuinely torn, and at other times, I think he would like me to be his best buddy. I mentioned something to him about going to see a show and he said "you went on a date! - that's so great." Just remember that these are just words. I highly doubt that he'd be happy to find out that I went on a date. Perhaps the idea relieves some guilt, but don't take what she says right now to heart. I personally think that you should tell her that it would be completely inappropriate for her to bring a date to see you. You are not her best friend or sibling and she needs to understand that you won't become that for her. Sounds like you should probably detach as much as possible until she starts to miss you - right now she has it all.
