If you haven’t seen her since high school, all of this could just be a fantasy and there is likely no connection in person.

I was contacted by a high school boyfriend couple times in my adult life and it was never just let’s catch up, it was always with romantic connotation. I had to block him because it was inappropriate. He was married. I wasn’t at the time but I was grossed out. Plus this isn’t high school anymore. Clearly he wasn’t happy in his life and somehow thought he could fix it by professing love to high school sweetheart who long moved on.

What’s not working in your marriage that you are looking for happiness elsewhere? Focus on your marriage, maybe seek counseling for yourself and as a couple. But I’d stop professing love to high school classmates. Focus on what’s real
