Gmail account hacked

My X devil boyfriend hacks my accounts and I don't know how in the world he does it no matter what! Please don't tell me to change my password..that's like me walking 10 miles in the rain and when I finally get somewhere to dry off..somebody hands Me a paper towel..not trying to be smart but this crap has went on for 2 years now. I have lost so much he will not give me my passwords. When I click forgot password it simply says we couldn't recover your account, then it gives me the link to try to recover it and I have changes my phone number and since he's been diddling in it he has PERSONAL PHOTOS and info that he literally trys to blackmail me with. He's a nightmare. But my whole reason is I love that Google is protective. But God knows when it gets to this point...where my x has full control over MY ACCOUNT, and I, MYSELF cannot even retrieve it then what part of that is right??? I mean if they were going to be THAT demanding for dead on balls ACCURATE info to be able to get BACK INTO THE ACCOUNT FOR THE USER, then it seems to me they should be that hellacious about not allowing the accounts to be hacked. I mean I've checked around, asked a few people and they went on telling me how they have lost so many memories and so much info based on things like this because Google just wasn't having it. And it's pretty damn sad excuse me for my opinion. But I'm big on memories ! Because however it sounds to u wether it be sweet, stupid or kinda lame, me not being a material kinda girl I think the precious things in life are priceless. MEMORIES BEING THE MAIN ONE! I have memories saved back of my decesced and none nowhere else. Literally. My house burned 2 years ago 3 months after I bought it and fully furnished it with new things along with every thing I and my mother ever had in our lifetime . Now I don't even have baby pictures or pictures of my father or family or nothing. It's like it's all been erased or swiped clean. I never thought I'd be able to get through that but I have managed. But thinking my things are okay with google, and them not be.. then demanding for everybody with a phone to use google.com or Gmail as our email service is just wrong. Gmail is #1 and unless someone tells me other wise I've lost what little bit I did have based on an idiot I don't care to be with anymore. And trust me I've locked it down before many times with questions, changing passwords regularly.. setting up other numbers and emails I figured he didn't know and turn email alerts on as well, well,.. I got the emails alright...by the time I got the message saying an unauthorized user has logged in from a unreconized web browser or device, I click this wasn't me, and damn If I don't suddenly get another message saying my password has been changed, then by the time I try to change it again or log all devices out other than mine, he's done edited my personal information to where if I needed my password code or link sent to my phone or email or anything else he's done put his own info and erased mine before I could even begin to try. This ain't fair!! I mean at this kinda freakin illegal??! I don't want to contact the law. Wish I could just get back in and stop this crap! It's more than just a Gmail to me it's ALOT more deeper reason than just some account. Please no negative comments I'd just like some help is all! I appreciate it !!
