Me and my ex was together for three years. We were very happy spent a lot of time together great communication.. but he begin to change he didn't like talkn to me, he didn't want to call or text often but he loved being around me. At first he told me we need to take a break and I begged him not to so we didn't a fe weeks after. He told me its not working and we could still be friends, but he saw why house number on theer id and thinks I told his mom about him smoking weed but I really didn't... he is so stubborn I tried calling and txtin him but he don't reply bak he blocked me on Facebook and avoids seeing me in store and he say ba things about me to my friends or people he know that's going tocome back and tell me, however I don't think he has jumped into another relationship. I really want him back, I miss him to death we were enaged and now he hates me for some I didn't do... how can I win him over fast?

You can't.
Sorry,but leave him alone-whatever his reasons are,his behaviour is not acceptable.

Find your selfrespect and start moving on.

I don't think you can win him over, but while he is mad, and being a butt hole, then you leave him alone.

Maybe he figures it out, maybe he doesn't, but making him madder helps nothing.
