How to get your brother back nice, when his girlfriend turned him mean?

1.Talk about the good, great, perfect times before she came along?

2.Get close to his girlfriend, and get all of her secrets and tell her not really things so if she tells, then you tell your brother, and say what a good girlfriend YOU HAVE! She might tell you behind his back. YOU NEVER KNOW WHAT THEY CAN DO.

3.last tepe GET IT AND SAY SHE IS CHEATING ON HIM?

First if he is in love with her talking to him is not going to do anything, he will just become combative, really the best thing to do is be there for him, and wait for it... if she is changing him he will get tired of it and then rebel against her, then its your job to jump in there and be the best sister you can be, he'll come back, you his sister, Ive went threw the same thing, and have totally went against my family for a woman, but when the goo hits the fan... and it will, my sister was there for me I know she always will be, now I have no problem trusting her read on whoever I go out with knowing that she just wants me to be happy.

I think your best option is to step back to a safe emotional distance, and let him see for himself where his behavior is leading him, and let him come back to you.

Trying to change someone who doesn't want to change only makes it worse, as do games and tricks, so be patient until it clicks in his own brain, and he decides to mend fences. Be patient, things will run there natural course.

Please don't try any of the dumb ideas you are thinking about doing, the are tricks and traps that will backfire, and have you looking VERY FOOLISH, and mean yourself!

If u talk to her about the good times and if she really loves him and they were meant to be then they will eventually start talking again. But it depends on the reason they aren't together anymore
