Congrats, dude. Great feeling, isn't it? Three months is no time at all, either. Some guys go years.
Yeah, I read a lot of red pill material, went to the gym and started working on myself.
The words of Rollo Tomassi - Hate isn't the opposite of love, it's indifference.
This cleared a lot for me. Even if I kept hating her, I am still thinking about her, this kept me in the cycle for frustation.
I still talk with her, sometimes, but now I get bored easily.
