Would you forgive your other half like Gavin Williamson's missus did?

Do nothing. If Gwynnie and Chris Martin can remain mates what's the big deal?

Keep an eye on situation and do some subtle detective work

Make some sarcastic remarks to they know you are watching

Go mental and insist they unfriend the ex immediately

Forgive and forget - the fact they told you shows deep regret

Ask for an explanation and suggest counselling

Rant and rave but then try to forgive

Call time on the relationship straight away

Have faith they will tell you in their own time

Confront them immediately and ask them to cut all ties

Wait until you catch them red-handed then take break from relationship

Plot your revenge before dumping them

Talk it over with them

Relegate the cheat to the sofa for weeks then try to give it another go

There is no way you will let this cheat back into your life... unless they grovel for a few months

Burn their clothes and change the locks. It is OVER!
