Does this happen to you? everytime i see a guy that ressembles the person i used to like, i start to like them?

OH I totally get what you mean. You haven't gotten over the other guy completely...and may never. That's not a bad thing...that doesn't mean there won't be other guys, but there will always be a place for him in your heart. I COMPLETELY understand. My first love...me and him will always love each other, but it just wasn't possible. I know you don't mean physical traits, but the thing about my first love was that he had dark blue eyes, and dark blue eyes, and I mean dark blue as in sapphires, are actually quite rare. His eyes always got me...this past summer I met another guy with dark blue eyes, and it was like WOAH where did you come from? I fell hard for this new guy...and yes, I also can't help but notice when a guy resembles some sort of trait my guy had. Sometimes if you can't forget a person, then maybe their supposed to be there? Yes, try branching out to other guys, and ask yourself, do I like him just because he resembles so in so? Or do I like him for him? But also, try reconnecting with this old guy. Maybe let him know how you feel, because it definitely sounds like something is going on. Things WILL work out somehow...good luck.
