"Can anyone on here actually say they have found "the one"?"

Yes. I can. Me. I am "the one" for myself. Not being cheesy or or funny (some will take it that way, but they can kiss my arse). Everyone is different and I find I am working best right now on my own outside of a relationship. Do I still want to be in a relationship with someone else right now? Not really. Do I ever want that though? Hell yes. I have wanted that in the past and will want it in the future. I am just happy being single right now. And I am also happy in general. Do I have ups and downs? Yup. You might consider listening to this podcast if interested in caring more for yourself, self compassion, self love, and even self marriage: The Soft Shoulder Podcast

Now. Some people may work better as a couple and really want to be part of a couple. And I do not know everything. But this is just a topic that I'm learning about because it interests me.

Have I ever been with someone where I thought "he's the one." I will be honest for you: No. The closest I came was a relationship I was in in college. But it didn't last and I'd like to not divulge details. I was young though, and I was never like, "I want to marry this bro." Do I hope to find the one someday? Yeah. But I also think our society is SOOO set up to make people think and feel like if they aren't in a relationship then it's so sad and all their fault. Neither of these things is true. I mean, sure, it could be one's fault if they have a lot of character defects. But then you just have to work on yourself. There's nothing wrong with being single.

"Am I chasing something unrealistic?"

Maybe. It depends. Are you looking for personal happiness from a relationship? One thing I'm learning is not to do that. Relying on others to make you happy is the best way to be sad. Happiness comes from inside yourself. Not someone else. I mean, yes. Someone else can make you happy. And should never be abusive. And there are dealbreakers. But look at the link in the next answer.

"Has anyone found their special someone who makes them happy? And I mean actually happy, not just happy for show?"

Don't rely on someone else to make you happy. My answer for you is I have been happy in relationships, and I have been sad in those same relationships. Relationships have ups and downs. And yes, we NEED connection and sometimes even sex for emotional health and wellness, and happiness. But what I'm learning is not to rely on someone else to make you happy. As long as they're not abusive or a jerk, as long as I feel an attraction, and they communicate as well as vice versa, I'm good.

All I can tell you is where I am, what I know and am learning. And that I am happy in my life.

Good luck.
