Loss on top of loss

I know it's the emotions running high.  But it just feels like loss on top of loss on top of loss.  It's not enough that I lost the man I loved and lost any sense of reality and ability trust.  It's all these other little things that trigger the tears and grief all over again.  Today it was my first credit card ever, going back to college.  I even remember the first purchase I put on that credit card.  I stupidly added my ex-husband to that card after we got married as a secondary card holder.  If he had been just an authorized user, I would have been able to easily remove him but they can't remove a secondary card holder who has accepted responsibility.  So now I'm forced to close this account.

I know this sounds really silly but sometimes small things are meaningful and often many small things can add up to something much larger.  This is but only one example of the many losses I have experienced as a consequence of his decision.  

And it just doesn't feel fair.  He hasn't faced any such losses like this.  He's not even having to deal with the painstaking process of changing his name.  I feel like I'm bearing the brunt of the burden of his decisions.  And he doesn't care.  He doesn't care the pain he is causing me.
