I have come across this situation several times over the last forty years and in different parishes and circumstances.
Questions I have for both of you:
- Are you aware of any other affair over this existing one that your wife may have had?
- Is the third party now in constant daily contact with your wife in normal circumstances eg work, parish, school, teaching or social / sports / fitness clubs??
If the answer to question 2 is yes then you must work very hard to extricate her from that regular contact. Yes, change the job, always attend with her whenever she is at the parish, pull her off - voluntarily the teaching classes or change the social sports or fitness clubs membership permanently.
The changes above only would apply to her regular contact areas with the third party.
In the meantime it is possible that most other members of your parish know exactly what has been going on and that you are the last to know that they know!!
If the answer to question 1 above is yes…then the rebuilding has to be applied to her serial behaviour. ie how or why does she make herself vulnerable to the obvious temptations that are before her.
I am sure all is not lost if you are both still active in all areas of your current marriage…
First, find out the truth in 1 and 2 above, then definately on a non-confrontational basis ask her how she thinks the current matter might end. Because, end it certainly will it is only a matter of how and when. That last point maybe too direct put like that but work your way round to eliciting her real underlying wishes. The fact that she is still active in the parish (inner circle) almost certainly means she wants the affair to end. She presumably attends regular reconciliation which means each time she undertakes to stop it by avoiding the occasions of sin and temptation. In the meantime she probably can’t help herself each time the occasion confronts her - daily?
Pray, pray, pray and pray again. She is also praying too and probably quite desperately. Prayer means action too for both of you but you must first of all work out the strategy - alone. Then talk it over directly with the Lord preferably at adoration. (Your wife might even be praying on the same lines at the same time hoping that she can somehow end this terrible repetition) I believe with prayer you will come up with the key.
Ultimatums (a)? are non workable in these situations because she cannot see through the clouds of red mist that are surrounding all her senses at the moment.
I will pray for you and I am sure you have the ability - with the help of God to come out the other side fully reconciled and with both of you accepting and giving forgiveness. Place the whole matter at Our Lady’s feet and give confidence to the Lord that you know He will sort it out.
God bless you both and your whole wonderful family.
