How do I stop being toxic with my boyfriend?

Me and my boyfriend been together for nearly 3 years
Im a really sensitive person
I get insecure and jealous easily
So I start drama with my boyfriend

We have broken up few times over this
But he still gives me chances and takes me back

I really need to change
I want to
For the sake of our relationship

How do I stop causing drama?
How do I stop being so insecure with myself?
How do I stop being toxic?
How do I stop being toxic with my boyfriend?
