Jealousy??

Alright ladies so I've been thinking a lot and reflecting on some past arguments I've had with my boyfriend because we had a good discussion recently and I want to make sure I keep putting my best foot forward when I have a concern or something upsets me and vice versa.

Before entering my current relationship I was cheated on by all my exes and it's safe to say it's left me with some damage. I get jealous very easily and I can't help but get angry when some girls approach my boyfriend but I get even angrier when I realize what I'm doing and how I'm feeling cause that's just toxic. So does anyone know how to kind of stop being jealous? It's childish and I really want to stop my behavior and let myself to be more trusting.
