What's going on? I went out with him in my early 20s for 5 years. We lived together, travelled together and he was my first love. But he was a selfish and self obsessed and in hindsight I had a lucky escape. I've been happy with my DH for 18 years, we have 2 great teens and a good life. So why do I keep yearning for the past? I've not seen my ex for many years. I know he's settled with someone quite a lot younger than me and they have one young DC. I was the one who ended the relationship and never looked back until recently. Just can't understand why.
