Ok, look at this from either your point of view an/or the g/f or b/f point of view. Let's say you were dating someone for 3 years. The relationship had it's fair share of problems, but both couples love each other dearly and had some great, one of a kind times with one another, not to mention it was a first true love type deal. Now let's say one person moves away to another state and returns a year later but doesn't want to be together anymore because he/she is afraid to be committed again and basically petrified that it will end up bringing all the bad shit that happened back to the forefront. Now lets say just by a random occasion you see your ex. Do you think the encounter would most likely spark those feelings of love and attraction again? Perhaps one reason why one wanted to avoid the other was b/c they were trying to protect themself, they still have feelings for one another but are afraid to be committed with that person again for whatever reason. Seeing that person would still be hard though, no?
