Ugh... not again!

Why, when I love my bf more than anyone, or anything, do I keep screwing things up between us?!?!?!?!?! I don't mean to, I just seem to do it.

Now, I don't mean "accidently" hooking up with someone else, or anything of that sort. That'd NEVER EVER happen. It would be on purpose! I kid, I kid!!! He knows I'm faithful to him and don't even look at dudes sideways.

No, I'm talking about forgetting important things. Like a bill, for example. I forgot to mail something I said I'd pay for him, to help out. After all, he deos a wonderful job always helping me out with stuff. Now, the creditor is calling, because it is very late. :( I said I would pay it, so the fault is all mine. I know that. I also know he has a right to be angry at me.
We have already had fights about money. His credit is awesome, and he doesn't want me to mess it up. I don't want to mess it up, either.

I hate when I make him feel like I'm not dependable. I'd do anything I could for him; yet I can't seem to remember to put something in the mail. I'm super reliable for big stuff, like picking up and dropping off the kids, meeting up with people for various things, making the bride look amazing on her wedding day! It's the stupid things that are common sense for everyone else that I seem to have issues with. I hate that!!

Maybe I should go to school for accounting or something. It would teach me how to handle money smarter, for one thing. I don't like knowing I let my boyfriend down. I have to find a way to fix this problem, and fast.

Ideas?!
