Struggling to socialize

Not sure if it's the right subreddit but I feel alone.

TL;DR: People don't like me.

So I was at an event recently, met a few people. Continued texting some of them even after the event.

But I feel like people don't really want to chat with me. I can see them texting in group chats but ignoring my personal messages.

Delayed replies, left on seen. Even when the conversation is light hearted and does not require much thinking to respond to.

It has been very similar in the past where I feel like the other person is weirded out by me and try to distance themselves from me.

And the irony is I'm an introvert who is always asked "Why are you so quiet?" at gatherings. As soon as I get a bit comfortable with people, they distance themselves.

I can swear that my texts are never "creepy" or sexual in nature. Just light hearted texts about life and work.

Or maybe am I not fun enough?

I've always tried to brush this off in the past thinking it's the other person but I can see a pattern now where somewhere I'm at the fault. And this is really affecting my mental peace now to an extent I cry before sleeping at nights.

Dont have many friends. Those who are, they just call me when they need help but don't ask me out for having fun or just random gossips.

What do I even do?

Please point to the right subreddit if this ain't the one. Thanks!
