I'm dating someone who has been cheated on. What should I do?

Just don't cheat on that person again, It will destroy Him/her and he/she can't trust ever again....

One's whose heart has already been broken is either tii cautious and unsecured or frustrated due to sudden break up and can go mental and emotional trauma.. As a human being .. I would always try to get my feelings straight with her from the beginning itself to avoid any difficult situations as such. It will be best not to give her a sudden jolt by ending up the relationship if I need to and rather be more open and understanding in the relationship. Finally I would try to avoid any reason for her that would hurt her again for I shall be with her through the difficult times..

Try and make them feel as comfortable as you can, it'll take a while for them to warm to you and see that you aren't that same person but eventually with the right support they will Come around. You have to take their mood swings and random questions that come with it but it's all part of the process

Don't cheat on the person. The person must have already been through a lot of sadness and scars on his heart. If you really love the person, don't give up easily on them. Don't cheat. The person should know and develop that fsith in you, knowing you won't do what somebody else had done to them.

Show them that you love them earnestly from your actions, don't make them feel insecure. Do things to create memories that will help them overcome their past shock. Tell them how much they're important to you in life time-to-time.

You should probably assure them that you won't be a cheater and earn their full trust and respect,slowly.

After sometime when they are not upset, talk to them about it. It's important that you communicate and try to understand each other. If they are still deeply affected maybe both of you should attend counselling/therapy together. This will show that you are supportive and committed to helping them out.

Talk to them about it. If it's a subject they want to discuss, then listen. If not, then be patient, they may open up over time.

Take your time with them because they probably won't trust you at first. Build trust so your relationship can progress healthily.

I think a lot of people get cheated on. I don't think it will have a major impact on your relationship, as long as you're not being "suspicious" or actually not being faithful.
