" I am just so tired of being sad". Wow, some pretty powerful words. You given a little insight as to your relationship dynamics (perhaps some jealousy/trust issues...only allowed to change the girls seems really odd to me) but only you know your own personal limits as to what you will accept in terms of behavior toward you. I will say that I can't imagine living and working with my partner all the time. That alone would be draining. I wish I had the magic answer as to whether your relationship is abusive, whether to leave or stay...you will find what will work for you. Can you find someone to talk to; a hot line or support group perhaps?
