Ali do nothing! As for your love at first sight happenings,may I boldly suggest that after doing it 4 times(I guess they were all your soulmate) and still being single and now suffering terrible turmoil and grief,disecting blow by blow every detail of your b/f's life and your relationship together that maybe a 180 is in order. Like letting a relationship mature and grow in the fullness of time, a looking before you leap.
" I've never dated...guess I'm an all or nothing kind of girl." I guess nothing is what you get. Ali you are no longer an impulsive teenager and maybe it is time to show some maturity in your choices and behaviour. I guess you are never far from a drama (indeed some people live their whole lives like this) if that is how you live your life but sometimes we need to do something different as per DB. I hope when you re read your posts it will bring you some more clarity, hopefully about you and not just the x bf. I say all this with your best interests at heart and hope you can see that.
