Back story, I was 17, working in the NHS, got forced to work with someone who I'd seen around and judged too quick, thought 'oh no', worked with said guy who was 19 at the time. Turns out he's actually great and so caring, we become friends quickly but he has a girlfriend and I find myself becoming attracted to him and I get the impression he thinks the same but he's respectful of his girlfriend. They then break up, it all comes out but he tells me he has to move to another country to study. Off he goes. My young teenage, at this point 18 almost 19 self has fallen in love with someone she can't have. We decide to remain friends. We add each other on social media, life happens, we don't speak like we said we would. I meet someone and have 3 kids. I've been with him a long time and married for 5 years. All is good. My teenage love also marries around the same time as I do. Has 2 children. Seems happy. We may have shared a like or 2 and an occasional happy birthday every few years on our public walls but nothing private. Today, I get a facebook message, 15 years later from him asking me how I am and saying that he was contacting me as he was watching my favourite sports team from across the globe. I say it's nice to hear. We talk about the sport, it's all a bit hit and miss, we have brief conversation about our kids. So why do I come away thinking so much about the past? Why am I even questioning anything? I didn't think he thought of me anymore even in a friendship capacity and I was just sat there on his list of friends. Over the years he's had clearouts of people he no longer speaks to and I am someone he no longer speaks to, yet he never removed me. He lives in another country (not even europe) and I would love to think that from teenagers to adults in mid 30s we could have some form of friendship but it's not realistic but why message? Why do I overthink?🤣
