Wishing someone happy birthday on Facebook, should I do it?

I know this question is pathetic but here we go.

Some dude ghosted me 3 years ago. It’s a real complicated situation but I wasn’t being clear in my intentions so either he wasn’t interested, or I confused him and he ghosted me because of that.

Anyways, I haven’t spoken to him in 3 years. I’ve been busy with life, I’ve been interested in other guys since him, and I’ve gone on some dates too.

I still kind of have feelings for this guy though… they are off and on.

His birthday is coming up, and I was thinking about writing him a simple happy birthday on Facebook.

I want that to spark up a conversation, but I’m 95% sure that it won’t. So if it doesn’t, at least I was nice and wished him happy birthday! Ha

I guess I’m only worried because I don’t want him to think I’m obsessed with him or something, even though we haven’t spoken in years. Logic goes out the window when it comes to this guy.

Opinions? Advice?
