When you catch your lover cheating on you, you have two options. Take them back and risk going through it all over again or break off the relationship and start your life afresh.
Your partner may be sorry for what they have done and promise to remain faithful in future, but can you trust them again? The doubts may never go away if you stay with your partner. But if you think you can hold on and help grow the relationship, then give it a shot. But make sure you dump your cheating half immediately even if you sense a small sliver of a doubt after the first incident. Or your mate may end up cheating on you, again and again, until you’re the one who’s left messed up.
