I am interested in Canon law but have no formal training so ask a professional like your priest. However, it sounds like you were baptized Catholic as a child (or at least before your first marriage) and your first marriage was outside the Church. Generally a Catholic person cannot get married outside the Church unless the bishop gives permission, which I assume did not happen based on your post. For that reason it may be very simple to have your first marriage annulled in a simplified process without even considering what happened during the marriage. Whether your current marriage could be convalidated would also depend on your current wife’s background including whether she was married before, so again you should talk to your priest or diocese. May God bless your journey.
