girls, I need to vent.. I don't need judgment..

Why am I so insecure?
Why do I feel so uncomfortable and sometimes even leave the room to cry whenever my husband and I come across someone provocative on tv or movie?..
I feel like I'm crazy..
Like mentally ill..
For letting something so dumb make me react like he's cheated on me although he hasn't given me reason to be upset.. ever..
It makes me heart ache..like literally..
:'(
I feel like I have a problem with just how strong this insecurity and just how bothersome I feel inside..
Being raised.. yes my dad talked a lot about women in front of my mom and he ended cheating on her and they just recently got divorced but.. I wouldn't think this is why..
I've always been strong..
But this kills me :'(
I hate feeling this way..
I try my best to stay calm but I end up getting angry at him for nothing and more at myself.. 
Maybe I wish I looked better for him but I am plus size and that makes me feel even worse..
I just feel so blah right now..
I can't explain it..
:(
