Hi there,
A lot of people are mean on here to other members.
I'm a new member though.
I'm not so great with advice but I have had been in a similar situation, probably like over a thousand times.
I've loved girls who were beautiful, smart, inspiring, witty and all other amazing things.
They were like angels to me and then I find out that those beautiful guardians are already taken.
Sadly, this happens a lot but please, don't start anything with this girl, if she leaves her boyfriend for you, she is most likely to leave you as well in the future. I'm not saying she will, I'm just only saying it is possible.
Nothing good comes out of being a relationship thief. And it really hurts. Her boyfriend probably loves her a lot and if he loses her, he could be deeply hurt. Now, how would you feel if you were him?
I've had guys steal my ex-partners in the past, it hurt me terribly, I sobbed for months, almost a year before.
I once loved a girl overseas, she came to visit me, she moved to my hometown and we became serious but then she slept with my best friend on my birthday and she dumped me twice. Once on Valentine's Day, again on Christmas Eve. I attempted suicide a few times, had to go through therapy and now I'm on anti-depressants because of her. And thanks to that b---h, I have loads of scars on my arms.
That's what it is like to lose a girlfriend to another man. It hurts.
