If a guy wants to take you out, he follows through. He doesn’t forget. He doesn’t wait for you to keep reminding him. He just does it. Especially when he was the one who showed interest first.
The talking at work, the long chats, the vibes those were real. But interest without action doesn’t go anywhere. Some people like the flirt, the attention, the almost. They don’t always mean harm, but they don’t step up either.
It’s not that you did something wrong. You were clear and open. He just didn’t match it.
I’d stop bringing it up and pull back a bit. If he wants it, he’ll feel that space. If not, you’ve got your answer without chasing it.
