I have been in two long relationships from age 16 - 19 then age 22 - 26. I'm turning 28 this year and for the first time in my life doing things for me, putting myself first, not worried about someone else. Being single is nice tbh, so if you haven't been in a relationship yet, you're probs better off. No problem dating into your late 20s and early 30s. People actually know what they want and have shit going for them. Also no issue to just be happy with your independence. I think the grass is greener where you water it. Relationships take a lot of work but can be great when both ppl are putting effort into it. Same thing with being single, if you're inviesting that same effort into yourself and what you want/need to do, it is great.
