Home wreckers: what forced you to marry a cheating spouse?

So you fell in love with someone who is already married and he or she starts cheating on their existing spouse.. you carry on with the drama as you think you found the love of your life.. but why should you trust this person who just betrayed their soul and ruined the lives of their partner and possibly kids etc.

Would you go ahead and marry this person especially after the fact that they just displayed dis-loyalty and something they would do again in future? Because normal response to redditors posting my spouse cheated is DO NOT LISTEN DUMP HER OR HIM BECAUSE IF THEY CAN CHEAT ONCE THEY WILL CHEAT AGAIN..

so just trying to understand who are those elite ones that marry a cheater?
