These threads are heartbreaking, that is why it breaks your heart. It is still part of the consequence of the first marriage and her infidelity, maybe even he knew he should not have married the first wife, but those choices, have consequences good or bad.
This is why divorce is evil. So many are in the same situation as the OP. there is redemption, but if you live in this life you will be injured by others. That is why Jesus came to begin with. We have options, the Church gave us those.
The whole topic of divorce, single-again, remarriage, and annulments (not necessarily in that order :|) is just painful. there is not much written to help anyone navigate when you have remarried, other than the annulment part. There is no emotional support for doing what is right. It is just HEAVY. All around. But it is a cross, that is the cross you must carry if you are in this situation. Regardless of who caused it. OP has some consequences, as does the ex, and the present “spouse”. It just is heavy, and there is only the guidance of “apply for a decree of nullility”…but since it is legal, you have to prove it. There is zero emotional support though. There is no ministry to assist, so there is a real need. I have felt banished somewhat because of it.
I live as brother and sister, not by his choice, but I had to make this right because he wouldn’t. So I understand the weight. Try to discern marriage in this situation, with most saying that they see a marriage, when the church says it isn’t one, they say irregular, invalid…people feel bad for the HIM in my situation, and attempt to counsel it as a marriage. When as for now, all it can be is a weird-shaped friendship…if there is at least that. there is always hope.
But the things you can control…your own behavior. Trying for an appeal and proving the marriage was not a real one. Regularizing the new union…
It does feel like rejection, but I think it is more my formation that tells me that. Too much television and gooey “love” what is love? God is Love, and he defines through His church what love is supposed to look like. Pick up a catechism. Look at the book “Love and Responsibility” if it isn’t right via the Church, then…it isn’t right. You can make it right. One way or another. (and the rules apply in other churches they just don’t know it)
I am sorry about this if it makes anyone angry. this guy isn’t alone. The woman at the well comes to mind. Jesus told her about her life. She had been married 5 times and was living with someone. She was told in the Bible and real life “Go and sin no more.” That is what I choose.
I don’t know if this is even helpful, but I think I am glad I got that off my chest.
