Annulment is not a Catholic "divorce", it is a procedure according to the Church's Canon Law whereby an ecclesial tribunal judges whether the a marriage was entered into validly. The Church presumes that a marriage is valid until proven otherwise. A "Declaration of Nullity" is not a dissolution of an existing marriage, but rather a determination that a marriage never existed. Typical resons for an annulment are a marriage entered into fraudulently by either party or under coercion. "Because I got tired of him", "she cheated" and "I found someone who makes me happy" are not reasons for annulments.
For the record, many ex-Catholics become ex-Catholics because they have divorced and, according to Canon Law, are habitating in a state of adultery. Does this apply in any way to your decision to leave the Church?
Of course “annulment is a (Roman) Catholic ‘divorce.’”
Rome spends pages trying to finagle its way around its own permission to divorce. If the money is right, the marriage never took place.
Hypocrites.
