No guessing needed about Catholic doctrine — just check out the Catechism online at http://www.usccb.org/beliefs-and-teachings/what-we-believe/catechism/catechism-of-the-catholic-church/epub/index.cfm
In brief: Grace — Christ’s divine life in our soul — is essential for salvation (by grace you have been saved), which is infused into the soul usually through the sacrament of baptism (Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins), which may be experienced as a baptism of desire or martyrdom in unusual circumstances. The supernatural life of charity grows by means of other sacraments — confirmation, the Eucharist, confession, anointing of sick, sacramental marriage, — as well as works of mercy. In fact, physically receiving Communion is obligatory only once a year (the so-called Easter Duty).
Accompanying Charity are the theological virtues of Faith and Hope. Thus, Catholic theology points to an objective transformation of the soul, a New Birth, worked out in the Church, the Bride and Body of Christ.
Because sacramental marriage intertwines with everything else, the Pope is calling for a re-examination of remarriage — which becomes adultery when the previous marriage has not been annulled. The question facing pastors is if someone FEELS sorry about their state and wants to amend their life (repent), what ACTIONS of repentance return the soul to an OBJECTIVE STATE OF GRACE — and what is the Church’s role in this reconciliation.
These are very complex questions that impact a person in time and eternity. Given the high number of remarried Catholics, the Pope wants the Bishops to work on an answer — and starting out, it hasn’t been pretty.

It's not complex at all. Go to confession and stop committing adultery. Either rejoin with your real spouse or life a chaste life with the current one. It's that simple.
