One of my closest friends is like that. I've known her for 14 years (literally met the first day of college) and she's been single for a total of about 2 months since I've known her. Her relationships last years so she's only really dated 4 guys until now but still, it always amazes me how she suddenly finds herself in relationships when she's barely dating.

It's definitely an attention thing for her. Once she and her guy hit that super comfortable phase where she isn't the center of the relationship, things usually fizzle out from there.
