I know divorce is wrong in the catholic religion but can you seperate from your spouse?
one can separate from the spouse for good reason, such as to escape abuse, protection of the children, and can even obtain a civil divorce for good reason, such as to protect home and other assets, insure support of the children etc. What you cannot do is separate for selfish or frivolous reasons “I want to find myself, we are growing apart, I need some space”.
What a Catholic also cannot do is remarry following divorce, unless and until the first marriage has been investigated by the canon law tribunal of the diocese and decree of nullity has been issued. Nor can a Catholic shack up with somebody else after divorce, or even begin a romantic relationship.
One should not take this step without pastoral counselling, and you will be advised to take every means possible to preserve the marriage, including counselling, marriage encounter, retrouvaille etc. If you parish offers no help call the Family LIfe Office or Catholic Social Services in your diocese for referrals.
again, wrong forum for a marriage question, should be in liturgy and sacraments.
