If they are emotionally gone, God didn't intend for them to stay. Let go and keep moving forward. Never turn back. Letting go can be easy. Forgetting can be hard. Let go of your pride and ego. Let yourself be happy. Be free.
Cheating doesn't mean you have to kiss, meet or have sex with someone else. Once you find yourself deleting messages so your partner will not see them, then you already are there. I agree Can't stand a cheater!
it hurts to let go, but sometimes it hurts more to hold on. letting go is hard and it hurts, but sometimes its for the best. if you hold on to something, it would turn out bad and ruin your future or friendship.
