They have such anger and resentment towards the other woman.The thing is that she's not the one who made the decision to unceremoniously dump you. Getting angry at his new girlfriend or seeing her as the enemy isn't going to help you in the least.He's laughing it off while you're steaming inside, possibly getting ready for yet another pointless fight which this time - may be the LAST one.
I can honestly tell you from personal experience (when women alluded my understanding) it came down to power.
Before I mislead you, it's NOT about gaining power over you.
Lots of men believe women have all the power to choose who they sleep with and they don't.
They believe YOU are the selector and they have no real say in the matter.
Your guy chose her over you and it's really as simple as that. That sounds heartless but you're not going to do one thing that will be insulting to her.
You're simply going to befriend her and him and show that you want to be a supportive friend to both of them.
And when things end, you'll be right there to pick up the pieces. You're likely very angry, confused, sad and empty.
You've been passed over for someone else and left to mend your broken heart all on your own. It's even more challenging if you're still in love with the man who dumped you.
You see there are lots of guys who may not believe they're good enough to hold a woman close.
Their self-esteem, past relationships, childhood experiences, all can keep them in a perpetual state of "looking for real validation".
The most effective way to get him back from her is to become his friend.
