Not a Grandparent

My step daughter has had a baby today. He’s Grandad. I’m nothing. Just me. It’s really weird. Like he’s got another person in his life. I don’t. I’ve been around 17 years !! I’m not a fling. I’ve seen his daughters grow up. It’s very very weird. I can’t explain it to him. He doesn’t get it. Thinks I’m being over the top. Others think I’m trying to make it all about me. 3 step daughters. All the grief over the years. And there’s been lots. I think im a dumbass for sticking around sometimes
