Tough goings, Target, but at least you've got a sign and a chance!
To add to Felix's thoughts, the reason to stay in a relationship is because you're better in it than out of it. That said, the first step (in my book) is to figure out what you want out of it, and as importantly, what *she* wants out of it. It's not about changing to meet someone else's expectations, but about caring enough for someone else to see that they get what they need.
*edit* And once you know what you both want out of the relationship, determine (together) whether you can both get what you want out of the relationship. If you can't, and there's no way to get there, then there's no need to wait the six months. If you can, though... then you can invest the six months in getting there, and make things a lot better along the way. */edit*
Counseling is always an option. There are pay options, and you can also go with a minister or someone similar. Those tend to be cheaper, if not free.
The hardest thing in all that you'll go through and discuss is to remember one thing when your beloved is talking to you... she's right. Whatever she thinks, says, emotes, or believes, she's right... because that's how she sees it. At the same time, whatever you think, say, emote, or perceive is also right, since that's how you see it. As long as you're speaking from the heart about how you feel, you are always correct. The two of you can have different interpretations of how something happened, or how it makes you feel, but that doesn't make either one wrong. You've both got to be able to talk to each other without judgment.
Next most important is listening... you have to not only hear what she says, but actually listen to it. And she needs to do the same thing
The old adage about having two ears, one mouth, and using them in that proportion holds true... on both sides. Don't interrupt to tell her where she's wrong, or why that's not the way it is. Listen... and then respond.
Bottom line... everyone goes through challenges and stress. Sometimes, they make you stronger. Sometimes they break you. As a human, though, you can decide which one it will be.
Good luck, amigo. You've got friends and support here...
