I hope God can use my post to get you closer to answered prayer.
What do you mean by jam my keyboard?
Have you tried taking the computer to repair? If you're tracked without court permission in most countries, you can sue such people.
Do you have any antivirus installed?
Avast | Download Free Antivirus & VPN | 100% Free & Easy Here you can choose Essential for free. Or you could go for Advanced if you wish, but I don't think the paid version has any noticeable advantages over free. Avast should be available for phone (although I am not sure how well it works, but you don't have anything to lose anyway, so why not try.) Antivirus will hopefully remove viruses and spyware. However, even the best antivirus software in the world would detect only 30-50% of viruses and spyware.
Just in case, make sure that you have the firewall turned on. I can't give you specific instructions, but here are instructions for Windows 10:

Another thing you could do is go through the list of installed programs
How to Uninstall Programs in Windows 10 and uninstall programs that look suspicious to you because she might have installed something to get access more easily. You should also do this for your phone.
Another thing to do is check what users you have on your computer. First, make sure that there are only users that you created. The attacker may have created a user account to make it more convenient for her to come in. So it would be good to delete user accounts that you didn't create on that computer. Here are instructions:

If there is a user who doesn't have a password, everyone can use it to get into your computer. It is also wise to change the password of your current user account. Just in case she knows it and uses it.
It is also useful to change the passwords of things that she hacks. For example, if you suspect she has access to your email, change your email password. However, changing passwords for your emails wouldn't help much until you clean your computer of spyware because when she has control over your computer, she could just copy your new password from your computer. So it is still important that you read and try to understand and follow my instructions in this post as much as you can.
There is also a chance that there is no infection in your computer, but she just hacks your router or Wi-Fi network. The problem is that default Wi-Fi/router passwords that come from the factory are known to everybody, so one does not have to be a genius to hack a router with default passwords. If you have not changed your Wi-Fi password so far, you should do it now. Make sure you have a long enough password (8 letters should be okay, 5 or less would take only a few minutes to hack). This way, you could lock her out of your Wi-Fi. In addition to the Wi-Fi password, you should also change the router password. If she knows the router password, it means that she could simply log on to the router and learn your Wi-Fi password from there. So updating the Wi-Fi password would give you only a little hope as long as you don't update your router password. Thirdly, remove any port forwardings from your router's configuration. And finally, set encryption for your Wi-Fi network to make it harder to hack it. Or here's one pro tip: Use an internet cable instead of Wi-Fi. This makes spying very difficult because no information is sent over the air. Although this would only be helpful if you suspect that she has physical access (that she is physically close enough, 10-20 meters at most, to hack your Wi-Fi). Sadly, I can't give you any tutorials for that because every router works differently.
If you get stuck with that, you can either seek help from a local technician at some computer shop or we can arrange a time when I take a look at your computer over the internet and try to fix as much as I can. Although I have to let you know that even though some specialist checks your computer, there is no guarantee that the problem goes away. If after getting help from experts the problems continue, you can come back here for more help.
