Ex and friends.

This is basically a vent, and I apologise but I have to get this off my chest.

I broke up with my then boyfriend literally 12.20am on New Years, I found out he'd been cheating in September and I tried to work though it, which I half did, then the whole night he was guilt tripping me, saying I didn't love him, I was cheating and just generally ruining my night. I was devastated but I needed to get out of that.

So five/six months later and we're on speaking terms, I won't meet up with him but we occasionally messaged each other just to find out how the other is doing. It was going well, he had a new girlfriend, and I was still preparing myself to date again.

So now I'm seeing the most amazing guy, and I am seriously so happy with him (it's still early days and the honeymoon period hasn't warn off can you tell?) but my ex is deciding to message me all the time now, apologising, getting depressed and suicidal and I just feel like it's a guilt trip because I've finally moved on from him. I know he recently broke up with his girlfriend but I just feel like now he's trying to ruin my relationship. I know everyone's like "just cut him off" but he cut everyone off while we were dating and he's literally got no one but I don't want his shit and stress to be put on me. You can't talk to him either because he just gets weird, and then starts the shit again the next day.
