You never love two people the same way so you can have another who will love you as much if not more than that girl but you need to ask yourself are you seeing others girls with the same way you felt about her because if you are your relationships will be doomed because you cant put the past loves standards on another present girl they are individuals and love differently.To say you dont do it like so and so is cruel because even the past girl will have treated you badly to your expectations at some point.Can you really go into a relationship with the past girl so prominant in your head because if you are you are only looking for a clone.
My exes have all said she's not you and i reply no she not but their are things you love about her that you disliked in me.
Let the past have her standards and the new her's.
It may not be as intense as the past but it will be intense in another way,we all look for love but no one ever finds the ONE who will love you as you want to be loved andthis is good because you evolve and learn more about how to love and be loved
A mistake is always forgivable, rarely excusable and always unacceptable.
