I cheated, should I break up with my partner?

What you should do it talk to your partner about this, see if you can work through it. Cheating usually is caused by unhappiness in the relationship, if you talk about them and try to find the issues you're facing you can together discuss what's better for the both of you.

An old wise man once said "if you ever created with another person, go with another person, for if you truly love the first person, you wouldn't go with the second one in the first place"

First thing you should consider is to let your partner know about this. Being honest in this situation may be best for you as well as your partner. The decision to break-up with him/her should best be made after that. If you want to stay with your partner, disclosure and communication is the best way to sort it out, may be even make the relationship stronger. It depends whether you want to break-up with him/her because you don't love them anymore, or because you feel bad about what happened. If it is the former, then your partner deserves to know how you feel about them. Because, break-ups are hard for both partners in almost all cases. If the reason is latter, then make an effort to let them know about what happened. It takes courage to disclose what has occurred. Sure it may feel awful during the course of the conversation, but trust me at a later point you will feel good about yourself for having come clean.

If you love them, just tell them the truth and who knows what'll happen. If you don't, try to explain to them that you cheated and you wan it to end (even though it feels really horrible).

To be in a relationship means having to be loyal to your signifant other. This is a no-tolerance zone. If he/she cheated, how can you guarantee that he/she will not do it again just because you gave them a chance? Giving them the trust and the chance just means having to deal with a lot more heartbreak than the first one.

You should talk it over with him. But be verry aware that if he can cheat once, he can cheat twice.

Your options are to either tell them or not tell them, coupled with break up or not break up. If you tell them, they will be sad and either forgive you or break up with you. If you don't tell them, they can't be hurt, however you may feel guilt for the rest of your relationship. It all depends on if you can handle the guilt. Weigh the pros and cons.

I think you should speak with your partner and find out how they feel about this. Explain how you feel and why you did it

Yes if you cheated then you should break up with them because it is being dishonest to both people unless you tell them and their okay with it then

If you cheated on your partner and feel that you cannot confront them and apologize, or are in the situation you feel you no longer love them this may be the best course of action.
