My daughter got through college still attending Mass regularly, but in the last 2 or 3 years her faith has faltered. She says she still believes, but she does not attend because she is in an ongoing state of mortal sin. There are other things which have negatively impacted her faith. She is now engaged for the second time to the same young man about whom we have some real concerns, which we have expressed clearly to her. He is also a baptized Catholic. His mother told me during that their first engagement that she hoped my daughter would be able to bring him back to the Church. But it appears that the opposite is happening. During their first engagement they were planning a Church wedding at her request. This time they will not be married in the Church. I understand that this would be considered an invalid marriage. Despite our heartache and deep unhappiness with this marriage and wedding, we would probably still attend. However if this would be wrong for us to do, we will tell her so and will not attend. Help!
