What would you do in my situation? I have a Yahoo email account and I want this hacker/stalker to leave?

me alone. If I take the matter to the authorities, which at this point, sounds very appealing, I am going to need proof, he has signed in from his device. I asked a similar question and many of them said I am doing several things to leave myself open to hackers and one of them is having a free Yahoo account. So now I ask you this. What would you do in my situation.

These are the things that have been happening.

First, I have a very good feeling of who this is. Let's call him Mr. Hacker to keep the story straight. We used to be romatnically involved. He is very good with computers and computer software.

OK. I get an email from another guy. We'll call him Dave. It is a long email and I don't have the time for a proper reply. So I leave it in my inbox to reply to at another time when I have more time. I get in the next day and it is gone. I email him and ask him to send the email again since it has somehow gotten deleted.

We continue to email back and forth. A month later, I am replying to an email and suddenly, the entire email turns to italics font. I did not click on the italics icon on the font task bar in the email and I did not click on control and I on my keyboard. I then click on this icon above on the task bar and also try clicking control and I at the same time. Nothing changes the text back to normal. I then explain to him that I have a hacker and to please not mind the italics and that I did not make it that way on purpose. About 2 seconds before I am about to send this email, it changes back. As I bring the curser over to the send icon, I see the entire text change back and I say, "Oh no! Now he must think I'm nuts." :P, since he will not see it in italics. LOL

Another time, as I'm going to a website, doing research, I see the curser move (on its own) down to the start icon at the bottom left, the menu pop up, then the shut down/restart menu appear in the middle of the screen, then the computer completely powers off on its own.

About a month ago, I decide to join a Google group, which I do from another computer but I also, without thinking, sign into my old email account on that computer. About a week later, I go to see what activity has been posted on this group and I have been unsubscribed. This is a closed group that you must be invited to and I know they would want me as a member. So I would have had to unsubscribe myself, something I would never do, or someone else would have to sign in as me and unsubscribe for me or post such obnoxious things in that week until I signed in that they felt it best to remove me as a member. You would think I would get notices about this. Maybe those were deleted as well. Who knows? I certainly don't.

The latest incident happened when I created a new email address using a fake name on a public library's computer but left comments on a Facebook page I like very much that I had "liked" in my old account set up on my Windows XP desktop computer at home. He must have found my account, since I was going by the name Michelle and he knows how I talk. He then gets in to that Facebook accoount, changes my name to something silly, adds friends I did not send friend requests to, nor did I accept as friends and puts troll like comments on my friend's walls.

I would like to get ideas to avoid him altogether and not have him find me again and also find a way to get evidence of him hacking or just signing in in the future (he should not be able to sign in if I change my password but he always seems to be able to guess it, no matter what I use) and press charges against him.

Thank you so much for any information you have to offer. The more details, the better. No answer is to long for me.
