I 'unno, why is this a bad thing? The more the merrier. Just because you have a good relationship and life doesn't mean you should settle for that and be boring. Does the SL shit hurt her or you? Then why stop?
SL brings me friends, cuddlebuddies, and employment opportunities. It's single-handedly one of the most important agency granting networking tools I've ever used. don't be so insecure about who you are and your interests.
If SL deprives you of agency and makes you neglect important things, you were already doing it wrong, dropping SL won't fix that. You'll just find something else to replace it to excuse those fundamental character flaws in yourself.
