I think this really have to depend on what kind of relationship
that you all want. I think this kind of things is best to be
honest. anyone who wished to be in a sincere relationship must take
the burden of honesty and history of his partner. Subsequently its
up to the individual to determined how much he/she will mind the
past of his/her partners.
just to share my experience, i just got attached to someone and
showed her pics that i took with my ex. I told her that i dun want
to hide anything from her as i want to be honest about these
things. Usually, i think gals will appreciate this gesture. But the
rule is not to FLOUT IT and brag too much about your past
relationship. This makes your present gf feel very bad. So avoid it
at all cost! And if you do take this road, you must also be
prepared that she will start being honest.. so you had better
psycho yourself to be ready if you are not prepared to hear such
things. But I feel that if these things are not settled in the
early parts of the relationship, it will get harder to swallow
later on when everything just spills over and you tend to dig up on
anything and everything possible.
Call it building a foundation for a relationship...
