text: why don't people divorce even if they don't have kids and know each other's unfaithfulness?   this is a complex question with no one simple answer. but it general it comes down to boundaries. for some people, infidelity is a strong boundary that they will not tolerate being violated. it can also shatter trust beyond repair. but other people are willing to give their partner a chance to earn back their trust. still others stay married for religious or financial reasons, and some have self-esteem issues and don't believe they are worthy of a partner who doesn't cheat on them. there are more possibilities, but these are a few of the common ones. dr. barb nefer, www.bnlifeskills.com
