I want my ex back

I want my ex back for ages we broke up a year and a half ago.

After we broke up he went to a uni far away from me so I decided to go to the same uni a year later I hate this uni but I wanna get him back.

He blocked me on everything but I make fake accounts to message him he annoyingly blocked those too and I got banned from making fake Instagram accounts because I made too many so I now message his mum telling her I’m depressed and I have to talk to him this has worked now his mum loves me. He hates talking to me at the moment but I think he just needs to love me again. When he blocks me I make a Facebook not Instagram and I send him hate messages.

Oh yeah he has a girlfriend but I have messaged his mum bad things about her so I can break them up and it is working.. I don’t really know her but sometimes I make stuff up. My ex and his black gf has been together for a year but I was with him for almost three years so whatever he keeps saying he loves her but he can love me. They’re falling apart now I’ve spoken to his mum about her. so I will comfort him I hope and then I can get back to him.

I am still messaging his mum and saying I’m depressed and that the only person I can talk to is him and she made him meet me I went to his house. So it’s good. Also made my new friend at university message message him now My ex blocked me on everything.

Give me tips on how to move forward especially now his gf is getting out the way.
