Found adult daughter I didn't know was mine

UpdateWe are starting to text back and forth with questions and photos, I think we will be meeting soon and see where it goes from there. We are both trying to be positive about this, we are both I think a little guarded with our feelings along with all sorts of other traits we share and going to take it slow. Her father in-law just had the same thing happen to him through 23andme, I think it made her rethink it all. With all of the gene testing going one now I have the feeling these kind of things are going to start happening to a lot of men later in life.
