<human>: Can you give me a shortened version of the text?

Here's the background: About a year ago I ended my 2 year relationship with a live in ex. There were a lot of reasons- but it boiled down to the simple fact that he was immature, unable to manage his own stress and anxiety, and I had become both mother and punching bag. I couldn't take care of myself. So I left. In hindsight, he was unintentionally very mentally abusive. 

Today: After a good run of singlehood, I slid into a relationship with one of my partners. We've been happy and monogamous for 7 months now. This relationship has been an AMAZING experience. Such an eye opener. And I'm constantly grateful to be with someone who's so much better to me than my ex was. 

However: As we're sliding out of blissful honeymoon time, I'm being confronted with situations where I need to communicate things with him. Such as small displeasures at actions of his, or wanting xyz thing. Nothing of great magnitude. No great disagreements. 

I've always prided myself on being a great communicator. I'm very introspective and analytical and genuinely just want to be good to the person I love. But with my current boyfriend I've noticed that my ex's behavior towards me has imprinted weird anxiety triggers. For some of the smallest stuff I want to bring up, my brain focuses on how he's going to react to me. And it's been conditioned to expect reactions of frustration or dismissal as opposed to care, honesty, willingness to listen. So I put off talking and stew in my anxiety about figuring out what to say and trying to reassure myself that he won't react like my ex and that I have no reason to believe that he will. 

I just get so scared of seeming needy, bitchy, or difficult. And rationally I know why I've reached this point of anxious silence. But I can't rationalize my way to the other side of the divide where I can be sure my boyfriend won't react harshly like my ex did. I don't like feeling trapped by my past... And I'm hoping maybe some of you guys can advise on what to do.
<bot>: Ex was mentally abusive and conditioned me into anxious silence for fear of reactions. Now I'm struggling to communicate with my current boyfriend about trivial things.
