yea, I would set boundaries with things that you don't like. Or even if you don't mind and you know that you should (she's talking with ex's/other guys far more than she should) you should set those boundaries just so she knows. Once she knows what the limits are she'll be happier with you, and you'll have a containment for her and her effect of her.

...well, maybe not as far as Mick says, but if you set the boundaries you shouldn't feel nearly as needy of her.
