Honestly, my uncle and his wife are the only real example I’ve seen of work. I’ve read some other stories online but never met anyone in person… I guess TFs are pretty rare.
They broke up for 3 years in their 20s, both dated others (one of them even married someone else). Got back together at 28 and have been married 20 years. They don’t call it twin flames, but the way they describe their connection… it’s exactly that. I haven’t said anything but from what I’ve heard of their story it’s exactly right.
