How do I not tie dating to self-worth?

I don’t know if it’s just me, but I’ve had a string of confusing dating experiences lately that have been messing with my head.

First one: matched with a guy on a dating app, hit it off right away. We FaceTimed, vibed, he said he was attracted to me, called me handsome, all that. We planned to grab dinner over last weekend. Day of, he says he’s feeling sick with a bad cold and asks to reschedule. Totally fine, we land on the following Friday instead. He even says he wants to pay for dinner and apologizes again. We text mid-week like normal, everything seems good. But then Friday comes and… nothing. No text, no confirmation, no check-in. I waited a bit then followed up a week later which was yesterday with a casual “hey dude” and never got a response.

Second guy: we went on a date a month ago and had a great time. He invited me over after, was super complimentary, lots of chemistry. The next week he asked if I wanted to go on a hike, but I mentioned I had recently injured my leg and that longer walks were kinda tough for me. Never heard back. Reached out again later just to follow up last night, and again—nothing.

Third one just happened recently. We matched on an app, had multiple FaceTimes and long texting convos. Felt like a real connection. While I was on a trip, he randomly messaged me in the middle of the night saying he was thinking about me and smiling. We kept chatting for the next few days, all positive, good energy. We planned dinner for that Friday, and kept texting throughout the week like normal. Then day of, I texted to confirm and he tells me he spaced—he was out with coworkers that night and just apologizes. It’s been over 10 days now and I haven’t heard a thing since.

I guess I’m just trying to understand. These guys seem into me, say all the right things, show interest, make plans, and then just disappear without a word. I end up internalizing it every time and it really chips away at my self-worth. Why does this keep happening?

Yes, I’ve gone on other dates in between with different people, so I’m not putting my entire life on hold. But these were the ones that felt like they had real potential. It’s just frustrating. Feels like you make an emotional investment with no return, even though the ROI looked promising.
