Lostmunki, welcome to SR. I have found a lot of education, support and perspective here and hope that you find the same.
I would like to suggest that you do as much reading here as you can, especially the stickies at the top of the section. Also, it would probably be very helpful to get yourself to an Alanon meeting. You'll likely learn a lot there as well as get a lot of support.
Many here have a lot of experience, strength and hope to share--try your best to take it in, if you can. It'll do you good regardless of where this particular relationship goes or doesn't go...
