Corsten.
You are doing the same fucking i-love-the-card-you-gave-me-for-valentine crap that caused you to lose her.
Wake up dude.
If you want her back, something has to change.
What you want to achieve, she must
feel things when she thinks of you.
Not, "i don't want my ring back", that makes her feel nothing.
Ignore her -> that makes her feel she lost you.
Flirt with other girls that she can see -> that makes her feel jealousy.
do fun things -> that makes her feel missing out.
As long as she's not feeling it, she's not coming back, stop fucking txting that crap
Succes jongen, komt goed!
Stop doing what you're doing now, and do the exact opposite.
