PerfectVerse, I've already addressed your question but I just want to tell you that the insecurity just gets worse (at least this has been my experience). When dating, you know, I thought it was kind of cute, like "oh he must really be into me. He wants all of my attention, etc." Then you'd think that after marriage, it would get better. You are saying to yourself "well hey, I COMMITTED to you dude. I MARRIED YOU. Chill out." But for me it just got worse and much more extreme and there was a control thing going on there as well. And none of it was cute. So, I'm just saying, pay attention to the small signs you are getting now. You said yourself that NOW it is an issue because he is attacking something near and dear to you...but I would guess that the signs of insecurity were there before. I'm just saying don't think that a strong commitment/marriage makes it better because in my experience it didn't.
