When it happens to me, I make some sort of change in my life. New clothes, new hair, lose weight, basically anything that makes me feel like I'm on a new path in life.
Next, go find a woman to rebound with. That will also help you get a sense of 'moving on'. You don't need to be attracted to her, just use her for the attention and company until you get sick of her. NEVER keep your rebound girlfriend around because chances are she's a lousy match for you.
It all takes time. Keep yourself busy and any emotions you feel for her will eventually fade.
I want to learn the strength and resistance that you men on this forum seem to have against falling for these women.
Love just isn't worth it.
When you date lots of women, you find out that they're all pretty much the same with varying degrees of baggage. It's difficult to fall in love with all these damaged women while knowing you can get a better one somewhere else.
As for love, I wouldn't say that it's not worth it. Without feeling it for
someone you're just going to feel lost and empty. What you need to realize is that you CAN recover from a heartbreak and CAN find another woman just as good or even better.
After my first fiancée left me, I decided to never feel like that for another woman ever. I didn't even feel that way for the woman I married. Now for the first time in over ten years, I'm finally feeling it again for the girl I'm currently with. It feels great. However, I'm much more aware of what makes women unattracted to men, so I'm avoiding doing anything stupid like putting her on a pedestal, becoming needy, etc. I'm making sure I maintain my masculinity, my confidence, and my self-esteem. If she decides to move on, I'll be able to find someone else.
One word of warning: when you find suddenly out of a LTR, you're gonna be a little bit fvcked up in some way. It inevitable. Whatever oddball behaviors surface will eventually go away. When I kicked out my ex-wife, I found myself incredibly needy for women. I was NEVER this way, but it drove me fvcking crazy. It leveled out after about 6 months.
Anyway, I wish you the best of luck on your new path of life. You'll do fine. Getting your ass in gear to start your new journey is the hard part.
...and go buy a new shop vac so she has no excuse to contact you.
