Hi Gooboy!!!
I am (obviously) a girl, so I'll respond to you how I would feel about this situation from the girl's stand point.
All I've heard so far is....me, me, me ...what about her? Did you think about her? If I would've been in her place, I would rather have a mutual split and go on with my own life. I would never want to be accused of a "stolen" fun youth. No way!
So, please, count her feeling in as well. I hope that was not too harsh.
Good luck!
