MWD said the KEY INDICATOR of long term viability of a partner is NOT how much they love you, how religious they are, or how much you two have in common...

The most influential factor indicating the survivability of a partner in a marriage is their maturity level during crisis... people who RISE when things are at their WORST are the ones you want to live with for the remainder of your life

Can your spouse manage herself during crisis? Can she find maturity when things are at their worst?

is there ANY indication she might GET there so you can trust her again?

If you have no confidence she can find maturity in crisis, and you have no confidence she CAN get there given your situation, its very difficult to commit to her...

Until she can have you believe she can handle herself when things are at thier worst (somone hits on her in private for example) then you can't trust her until she CAN.
