*I would go. My sister was in somewhat of a similiar situation. She divorced, no annulment, and was living with a divorced man, who left his wife (and three kids, one of which was a newborn) to be with my sister. I was visiting Florida at the time, and she asked me to meet him. My kids were traveling with me, my husband had to work and couldn’t come with us–so we met them both for dinner. It was awkward. She knew my feelings about him.
I went to dinner, we had a nice time–and I always prayed for them. I prayed mainly that my sister would see she was living in sin, and would end the relationship. Guess what? She did! Praise be to God! So, keep the faith, pray that he ends this relationship. Nothing good can come from this relationship–God doesn’t whisper in our ears to leave our spouses, and have affairs so we can find ‘true happiness’…so this relationship truly doesn’t have God’s blessing whatsoever. That being said, be kind, polite…when asked for dinner, go. But, I agree with the poster to not bring your kids. If I had to do it over again, I wouldn’t have had my kids join us. They were 11 and 14 at the time, but still. It was so very awkward for them, I regret bringing them back then. They loved their uncle (my sister’s ex) so they were so visibly awkward at the dinner.
Pray pray pray for your brother. He needs prayers more than anything. I will keep you all in my prayers, too. Trust that with God, all things are possible. I never thought my sister would leave that man, but she did. And she came back to the Church, and is now considering the annulment process. I pray things get better for your family. :hug1:*
