This happened with me, i also wanted my ex back, and now i just want to date with lots of women :PNice work man!
That's a great breakdown.
When I started researching this stuff, I was basically looking for information on "How to win back an ex". But I discovered a LOT MORE.... like a whole new world of information I didn't really know existed.
So I dove in & studied everything I could find.
It was definitely an obsession for a couple months. (However, I had plenty of time since I had recently moved into an apt by myself.)
Luckily I began having success right away & started having real interactions & building a new social circle. Otherwise I might have become addicted to studying PUA material. LOL!!
But...my philosophy changed from wanting my ex back, to wanting lots of women. (That didn't last long though.)
After a couple months I realized I just wanted to be the best version of "me" I could be.... and to find ONE special girl to connect with on a deeper level than I ever have.
But one thing is for sure...
With every step closer to becoming the Man you want to be, other people DO notice & your life improves in soooo many aspects; NOT "just with women."
