It kinda seems like Megan is an emotional vampire. And perhaps you're starting to see why she doesn't have any close relationships. It sure sounds like she needs a lot of emotional support. But hey, if you've got it to spare, maybe it'll make a difference for her! But I do think it's crazy to sleep with someone on a first date and then wonder why it didn't turn into something long term. I think trying to find intimacy by having sex is very common, but I also think it doesn't work.
