Does being cheated on leave you damaged?

My last relationship was hell and my ex was very unfaithful and abusive. Though I do not love him anymore, and haven't for quite some time now, I can't seem to push past the feeling of fear and I'm always worried it'll happen to me again but with my new boyfriend. I get anxious when he's out drinking and I haven't heard from him in a while, and I get incredibly jealous if a girl even speaks to him. He's such a good man to me and no where near like my ex, how do I shake this feeling for good? I know it's not right to assume and I should trust and not intentionally burden my boyfriend with my crazy emotions but I genuinely can't help it. I'm so afraid of this happening to me again I know I couldn't handle it. I just feel like a damanged good.
