The problem is, I believe the relationship has a tendency to
fall apart if I don't change. Whether or not, I should is the
nagging question. Whether or not it is worthwhile, is another
question.
Melee,
If it's just bad habits, then yes.. you should change... for
your own sake. Be it financially, socially, personally... you
change to become a better person.
If it's changing so to morph into his ideal woman, then no.
Because he knows it's just not you, and when he sees what he wants
in another woman with all his desired demeanor.. he will have a
change of heart.
Be true to yourself... faking it won't last.
