I am so over his jealousy and insecurity it is exhausting being with him sometimes

My husband and I have been together for over 5 years, married for 3. He has always been somewhat needy/insecure but I told myself the insecurity would get better over time.

It has gotten better. But it never goes away. I’m 7 months pregnant with our second child. He called me while I was at work. I had him on speaker and while I was talking to him one of my employees came into my office, so I told my husband to hang on and put him on mute so the employee had privacy for whatever they were going to say. My husband immediately text me “you’ve never put me on mute before (I do it all the time when I’m at work) you must be hiding something or someone”

I am just so mad I am over it. I literally do everything for this man. I’ve never given him reason to think I’m cheating but he literally assumes the worst about everything. I just don’t know what to do, we’ve talked about it, it has gotten better generally speaking, but it never seems to truly go away. I can’t help but think is this really what I signed myself up for in my marriage? Am I really going to have to deal with forever??

I know people might say he acts like this because he’s cheating, but I really don’t think that’s the case. And he is going to counseling and trying to work on it but it’s still very frustrating. It still comes out every 3-4 months or so and it’s still too much. It makes me so mad and sad. Thanks for reading.
