Need advice ‼️‼️‼️‼️

So I’ve been dating this new guy since august

But my ex won’t leave me alone even though he told me to don’t talk to him

He will get mad if I don’t answer his calls or he will find any reason to “check up on me”

I told him multiply times to leave me alone he won’t he keep making different ig account just to talk to me

To “check up how I’m doing

I might be mean but I told him off this week

Yes I did block him over and over again but I just gave up

Now recently my ex manager I have spoke to her today

And she said a few things

So I went back to him and said

I’m tired of him especially telling people I got a new dude to offend him

I love my new man and this man told me multiply times he doesn’t want me or want to deal with me and I didn’t want nobody on my side to know I was dating and I didn’t want nobody to know I had a new bf the last time that happen there was nasty things that was said and encourage my ex to cheat on me since he had money and he was young and I didn’t want to go threw that again that was my privacy so for him to assume and tell every body especially in that way I found it very disrespectful and hurtful

And I don’t want to tell my bf he is the type to go looking for somebody and do what he got to do and I’m just trying to avoid drama

Also mind u this same ex has told multi people I’ve been dealing with a lot of dudes and accused me of cheating on him

Also text like this piss me off the hell u worrying about my pictures for

What should I do?

I need advice

Please

God bless you all
