I think you are making a huge mistake in giving up friends to placate your husband's insecurity. (I'm talking about the female friends.) I watched my mother spend her life doing that to placate my father, and all it did was turn my father into a worse person.

Your husband cannot possibly meet all your needs to have someone to confide in. I'm not a believer in married persons having close, confiding relationships with persons of the opposite gender, unless that is as couple to couple. But it is extremely unhealthy for a married couple to relate only, or mostly only, to each other. The two of you will just dwell in a mentally stagnant place.

You are doing your husband no favor with this approach. The best way for you to help him in his insecurity is to provide him with something healthy that he has to adapt to. A loving spouse can greatly help a person to grow and mature. Give your husband credit for having the potential to grow.

Cultivate female friends for yourself. Do not report to your husband on every conversation you have with such friends. Doing that just enables and encourages him to be insecure.

The approach you have described is you adapting to and accommodating his unhealthy tendencies. That's a recipe for regression for both of you. Instead, turn the tables. Engage in healthy interactions with others, and let your husband learn he has to adapt to that.
