I think. If you really like him, he will handle it himself. I told the girl. Minimize contact with him.
Don't mess with that woman, the more rational you are at this time. The more he realizes his mistake. If he doesn't care about your feelings. Then just tell him where you are. Ask him, what does this mean?
Attention. Be sure to grasp the degree if he has tried to correct it. Then you should take good care of him, or he will waver in his determination.
With his love, he made up his mind to let him leave that woman. Everything else is in vain.
However, different personalities have different ways to show their love, but anyway. Communication is the most important thing.
