I'm dating someone who has cheated in the past. What should I do?

You should give that person a chance and if that person cheats on you as well then clearly that person is not the right one.

Don't judge, maybe you the one person to change him. Only react when he gives you a reason to react. And then, keep going

If you dont feel secure in your relationship and are worried that your partner may cheat on you again, then you should probably have a conversation with them about your fears. It is very difficult to have a functional, positive relationship without trust and if you feel like you cant trust them then you need to decide whether or not you can deal with having that trust issue in your relationship.

I'm not a big follower on the idea that once a cheater always a cheater. However, you need to look within yourself to see if you are willing to tolerate such a thing and not let it affect your own personal life.

We all do mistakes you know .. but when someone cheats on you it's really hard sometimes .. you gotta find a way to make him confess about why he cheated you and why he fell into that .. and love each other more to the level where you never have to look for another partner :)

A relationship is all about trust, if you don't trust them to not make the same mistake again, it won't work out

Treat them like anyone else you would date. If you love this person and are willing to forgive their past, you have to accept them as they are. If trust is an issue, you shouldn't date this person, otherwise it will cause the both of you stress. Trust is the foundation of a relationship, you must forgive and build firm morals on each other.

Talk to that person about their past cheating and let them know it worries you. Whether a person has cheated in the past or not, it takes time to earn trust in a relationship. If you feel reassured after talking to them, work on building that trust over time. If you are not convinced, there is a chance that you will always worry in this relationship, possibly feel the need to keep tabs on them and eventually lose them by overwhelming them.

Everyone makes mistakes. You have every right to be concerned, but remember that everyone has past mistakes that they regret. It takes building trust to make sure you are confident with your partner.

You should try trusting first. Try talking. Because talking with each other always helps. Then if that person is still the same then move on. Life does not end there.
