My ex boyfriend is dating another girl
If someone agrees with him too strongly, he'll be quick to suddenly jump to her defense.
Don't suggest or point out anything bad about his girlfriend, because he'll feel you're attacking her.
In the meantime, keep yourself busy by making yourself better.
Hit the gym, and take your frustrations out in the weight room.
But at the same time, you'll be putting yourself into position to strike, so to speak, when the time is right.Be a friend he can trust, and that's about it (for now).As difficult as it may be hearing about your ex boyfriend's new lovelife, you're going to need to grin and bear it for a while if you want him back.In the meantime, you're clearing your head and taking your mind off the present situation.
If you play your cards right, eventually you'll become the 'go-to' person whenever your ex needs to bounce an idea off someone.
He'll do this either to protect your feelings (which is sweet), or because he wants to still leave the door open to a possible reunion (which is good) in case things don't work out with her.
