My fiance cheated on me, But i still love her

Sorry to hear about your situation bud =(
She cheated on you, and now sleeps in a different room? Doesn't sound good. If she did it once, she'll do it again. I would take out the trash.

Whatever you do call that wedding off. You guys have far too many issues going on here.

Supernova had it right. Concentrate on your kid, and let her wander off. If both of you are mature enough to put the child's welfare above your individual issues, then you don't have to marry her, love her or do anything for or with her. Leave her go, she WILL cheat again, they almost always do.

If you let it go, she's only going to do it again the next time she has a crises, doubt, or argument with you.

You're giving her a template to base her future actions from.

People make mistakes though every action should have an opposite and equal reaction, otherwise discipline gets thrown out the window and you live in a disjointed relationship of chaos and festering resentments.

Marriage is a discipline and there are no half measures in it. All or nothing.

Action A- Fiancee cheats
Reaction B- Fiancee is no longer fiancee and relationship is voided.

What happens after that is anyone's guess though the child is irrelevant to the situation. The child may not like any possible changes to it's structure but it will either understand or come to understand as time goes on and becomes comfortable in the new structure or environment. Trust me on this. I know it to be personally true. Kids are resilient and will eventually fight the pair of you should you ever make hints of getting back together way down the road since the child's structure will have monumentally changed once already. Kids want and need stability. They also need to be shown right and wrong and the repercussions of acting wrongly.

React true to yourself and the kid won't judge either of you poorly for it. Set the right example for her and for your child.
