Sorry you’re feeling so low OP
When I was 28 I felt exactly the same. I had a good job, good pay, I lived alone in a beautiful flat and I was so lonely. It genuinely felt like my life had no purpose.
What was the point in going to work everyday to earn money to spend it on nothing meaningful.
I was part of a close circle of friends, there were 5 of us, and I was the only one who wasn’t in a long term relationship, or married, or a mother or pregnant. I felt like such an outsider, it was like everyone else’s lives were going in the right direction whereas I just felt so stagnant. I was very jealous of the lives they had in comparison to mine.
One night I really snapped at my best friend, I was really nasty to her, I made some really spiteful comments to her which were all based around her being married and having a child - it was nothing more than jealousy. I was so bitter and unhappy.
I turned to online dating and met numerous men, some of which I went on a few dates with and some that I had absolutely no interest in seeing them again.
One day I went on a date with a guy and he was nice enough but I didn’t feel a spark. I didn’t feel particularly attracted to him and although I could chat away easily to him there just didn’t feel that ‘connection’ that I thought I should feel. It was almost like I was looking for love at first sight. I did agree to a second date though but I didn’t feel any differently towards him after it.
He wanted a third date but I felt so disinterested, I just didn’t feel any urge to see him again. I spoke to my best friend (the one I mentioned above) and she told me to just give the guy a chance and that sometimes love can grow and I need to give things more time.
I can’t say I bought into it but I took her advice and met up with the guy again. I don’t know what happened on that date but something just changed, things clicked, and I started feeling happy whenever I thought of him.
Anyhow - 4 months later I moved in with him, two years later we were married and now we have two children together.
I often thing back to when my friend gave me her advice because if she hadn’t then I would never have gone on that third date - and I wonder how differently my life would have turned out.
Sorry my post has been so long - I just wanted to show you that I fully empathise with how you are feeling and that it’s perfectly natural to feel this way. But I also wanted to show you how life can take you by surprise when you least expect it and before you know it you are walking down a whole new wonderful path.
Keep dating and as others have said, don’t be so quick to dismiss them because a few dates down the line he may turn out to be the man you eventually share your future with.
