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

It all boils down on what do you want to do? on what do situation you are in? The past and the present version of him are or may be different. Only you can judge if he's worthy of your love.

I would tell them that I'm not okay with that and make sure that they understand me in a positive manner because I wouldn't wanna loose the person whom I love.

Give him or her a chance, because everyone deserves a second chance we're all human, nothings perfect

Personally i believe that someone who cheats once will cheat again. Breaking it off and looking for a more loyal companion could be a better option.

Be extra careful this time..dont show him\her that you doubt them ..still doubt their every action, don't let the past repeat again.

Doesn't necessarily mean that they would cheat again, although it's more probable than not. Nobody can tell you what you "should" do as nobody can give you a guarantee about it. In this scenario, just do what makes you feel comfortable. If you feel uneasy and suspicious when they're not around and those feelings make you insecure to the point that it's having an impact on your productivity, sleep, and all the other important aspects of life, then it's better to move on and make a better choice. Hope this helps (:

Do not judge people on their past. But be cautious, if he cheats on you, it may not be the first time. Do not forgive him straight away. Give him straight away. If it happens more than once, or you cannot forgive him, leave him. Foucus on yourself before him.

The first question to ask is, how do you feel about his past? If it makes you insecure at the thought that he might cheat on you, the relationship won't last as there is no trust. If you think that you can work past this and trust him to be loyal to you, then the relationship is worth fighting for

Your past can say a lot about about you, but people can change. Someone's current actions and commitment to being a better person should speak louder that their past wrongdoings

Be aware of it know that this person might cheat and be ready and if he doesnt.. Congrats!!!!!!!!!!!
