Like everyone else I’ve been hacked

Actually, everybody else has not been hacked, except for a few key figures on the world stage such as political rivals, drug kingpins, journalists in repressive societies, because the cost of remote hacking runs into the tens of thousands of dollars.

Thus, your iPhone hasn’t been hacked, either unless you fall into those categories.

The text messages are SCAMS, pure and simple→Recognize and avoid social engineering schemes including phishing messages, phony support calls, and other scams

The other symptoms sound like Ghost Touch, a failure mode of the screen digitizer - have Apple check out your screen.

One possibility is your ex has hacked your phone, but that would only be possible if he had physical possession of it for about 30 minutes, and he knew your passcode. And even then that would not explain any of your symptoms; the most he could do is install spyware. And there’s a simple solution for that - restore the phone to factory settings, and set it up again→Restore your iOS device to factory settings - Apple Support

The FBI is your best resource. There are cases with high level government officials where mercenary software was able to be installed, but you are looking at someone spending close to $1 million dollars per device and you would also expect a wire tap on your cell provider and your physical activities being monitored by agents. If that sounds like you, then it is possible. Apple does provide a Support Article for those cases:

For the everyday user, Safety Check will do the trick and you can:

• Change your Password
• Change your Passcode
• Review the Trusted Phone number of your account
• Review data being shared with others
• Review other devices logged into your account

OK, I understand. It’s probably user error. I get it. But how come all through my settings I have these app clips that I cannot access and I did not put there. I don’t even know what they are… And I’m constantly getting notifications that somebody is trying to get into my email my Apple, my Facebook all that stuff

Well, someone IS trying to get into your email and stuff, but failing. That’s a good thing. Just make sure you have strong passwords and 2 factor authentication. But if you know who it is call law enforcement and file a stalking complaint.

Have you secured your Apple account any other account accounts?

Re: “… if anybody has any advice …”

One suggestion if you’ve been as compromised as you’ve stated:

Get another email, get another phone number, get another phone.

OK, at one time you shared your location with him. Did you cancel that? Open the Find My app, tap on Me, and turn off Share My Location.
