Kung kasal naman kayo, try mo i-work out and forgive him but never to forget. People make mistakes. Give the man a chance kung deserving ba. Anyone knows it has great risk emotionally but as a mature person, it's always great to become the better person. Kung hindi sana kayo kasal, it's much easier to disconnect him emotionally. It's up to you to decide, but personally, it's not like your life will become better if you get annùlléd/separated to him. Yes, you get back your lost freedom when you're single, which could be quite convenient, but there is always a price to pay. Pray that you won't be with someone worse than him in the future if you decided to leave him.
