Ali, men dont say "goodbye" the way women do. And men that are in a mess try to avoid saying goodbye. You told me your BF is an avoider, right? Goodbye would be too hard for him. So, he just let things fade...
It's not weird to still love someone after a year. I think that if you let it, you can love this person and feel hurt for yearS!!! It's all a matter of perspective and ...luck. If you had met someone treating you the way you deserve to be treated now, believe me, your mind would be off him.
Be patient. Just make sure your next "lows" are always a bit higher than the previous ones... love K
