[UPDATE] My [28/F] friend [41/F] announced she is getting married next week. I have reason to believe she is lying.

So after reading all the responses here, I became increasingly more concerned. A background piece not included in my original post is that all the players in this scenario are connected by a recovery community. Because of this connection, I knew the "ex", Ashley, some years ago and we were still on one another's social media. I decided to reach out and ask about James.
That evening Ashley called me and we then conferenced in James. As it turns out, he is married to another woman and they have a child. He and Ashley never dated and aren't even really friends, they simply used to chat at a large meeting that was also attended by my friend, Wendy. They believe that she saw them speaking there and created a delusion that they had dated and Ashley was now poisoning James against Wendy, all the while he was married to another woman.
Over the course of the last two years, Wendy has approached James at multiple meetings with declarations of love. He reiterated to her each time that he was married and stopped attending that meeting to avoid her. But oddly, she ended up at his meetings again and again. She approached his sponsor and friends telling them they were in love. She also approached Ashley threatening her with a restraining order because she believed Ashley was conspiring against James and her, as a couple, because they were "together" now. The second time she approached her, six months ago, Ashley called the police and made a report.
Until our conference call, Ashley and James didn't realize how they were connected and they didn't know the extent of the delusions. When I told them about the marriage date, they were very concerned. James called the police.
I called the emergency mental health line looking for help, but their only suggestion was to call the police and ask for a welfare check on Wendy, which I did. Knowing that she has no connection to James and is living in a complete delusion made me so concerned for her. Once the wedding date came and she didn't get married, what would happen? How would she mentally process that?
I was given a reference number and when I called back, was told they made contact but did not intake her since she didn't appear dangerous. Since the check, she has ignored my calls. The wedding date came and passed and I heard nothing. At this time I feel like I lost a friend, but she was already gone in these delusions and I did what I could to help.
Going forward, I hope to get updates from other people in the community that she is doing better, and hopefully abandons these delusions.
TL;DR: There was no wedding or relationship, James is a real person with no connection to Wendy, she was fully delusional.
