bloody hard work to keep the passion alive with someone you've been with for years not to mention life stresses - kids, finances, work getting in the way, i genuinely think a little extra-curricular fun so long as you're careful can keep a relationship going beyond the point it would otherwise last and like others have said already on this thread, seeking sex elsewhere doesn't equate to you no longer loving your other half i still love mine to bits and the kids even more so
