Exhausted from modern dating , is there any hope?

I 27F cannot understand why it’s so hard to simply find someone and grow with them. I feel like it shouldn’t be this hard. Why is dating so bad now? I’m fit , funny, very extroverted , great career , and get told I’m gorgeous so I’m not sure what’s wrong with me but dating has been so bad. I met a guy in hinge , had a great connection, became exclusive and I thought it had long term potential so I had sex with him last week. Right after he started giving me the cold shoulder , not sure why but a couple days later he basically told me he’s not read for a relationship and wants to take a step back because he realized he needs to work through some things from his last relationship and to leave his things outside of my door because he didn’t want to talk or even see me again.

It was a whole 180 and I’m just so confused and hurt on what went wrong. What was the point ? Why are people like this? I’m crying as I type this because I’m just… confused. It left me so discouraged and hurt I realize I don’t want to put myself and my heart through this again. Dating is so bad and I can’t even wrap my mind around why. This can’t be normal. I’ve dated people I met through mutual friends,dating apps, out in the wild and the outcome just seems to be the same. What is going on in the dating world and is there any hope? I turned 27 last month , im feeling older and like I’ll never find my person . I just want to be out of the dating scene
