see your pastor, give him all the facts on all marriages, civil or church, of both parties (plus their former spouses), which is a lengthy interview process. Ask his help in submitting your situation to the marriage tribunal of your diocese. the church considers a marriage to be valid until proven otherwise. Until the status of former marriage(s) is determined, the present marriage cannot be validated. Every case is unique, any info you get here can only be general, not specific to your situation. It may actually be easier than you think to resolve the situation, but your pastor needs all the facts. Please don’t delay, get started on this hopefully you will someday be able to convalidate your marriage, go to confession and return to the Eucharist. Offer up the time away from the sacraments for those who have no access to the Eucharist through no fault of their own.
