Mattie, I am sorry to hear about your problems. A septate hymen is only at the entrance of the vagina. You also get a septate vagina where there is a wall down the middle of your vagina. So it is almost like having 2 vaginas. Is this what you are talking about?
Do you have a clinic or community health center close by where you can see a doctor? It is important to have it looked out. Even if you have to make special arrangements for paying the doctor. Most doctors will also see you at a lower rate if you do not have insurance and explain your situation.
After a year of hardly being able to have sex, it will most definitely cause problems for your relationship. It will not just go away by itself. It is anyways important for you to have a gynecological checkup. It does not sound like a ObGyn ever saw you?
Best of luck!
