What to do if you have a cheating boyfriend?

In the first place you have to be serious about it in prayers. Then tell some one whom you think the husband respect a lot to call him and advice him about it and if still he is not changing, then you send him to his church pastor to also advise him.

in all honesty you should just step back and let things take their corse, if you get to involved your sister will hate you. i have been in your sisters shoes, it sucks but when you love someone you are blind to things like that. one of my exs was always cheating on me and i kept letting it go until he cheated on me with my sister and got her preg. if you really feel the need to do something you can sit down with your sister and talk to her, tell her that you dislike him and that you dont think he is good for her but dont push the subject to much. good luck

i understand she loves him a lot but he doesnt love her if he did he wouldnt be cheating on her all the time. she should ask for divorce even if she be unhappy for some time i guess thats better than being with a guy that is sleeping with other girls and then comes to her. thats an humiliation that she doesnt deserve. even they have a daughter together the best is that your sister asks for divorce. her daughter can still see the father. what is the most important is that your sister has a happy life. and with a cheater guy she will never be

Nobody can do anything with this kind of man. Even if you don't like your sis' bf you can't really do nothing bout it unless your sis' makes a decision to leave him. But until she tolerates what her bf is doing then that's it. Your sis has the final decision on what to do on her relationship with his bf.

We can't do anything.. The decision has to come from your sister. Believe me, it is hell easier to deal with the boyfriend than with your sister who loves him blindly. You can tell her all sorts of things to wake her up, but the thing is, does she want to wake up? Your sister will have to make that decision for herself.. Be there for her, just so she knows that even if she decides to split with the guy, she has a very strong support system. Hopefully, your sister wakes up before things get out of hand..

First, pray for him. Then ask your sister to seriously talk with her boyfriend about the problem and what is the best solution to do that both would agree.
