What can I do to bring my relationship back to life, my fiance' has interstitial cystitis?

Shes a B####... she has no feelings for you dude get over her and find a LADY that will appreciate all the wonderful things you are doing for her now life can be glorious when you have HARMONY in your life.She will have to get on some meds to bring the inflammation down so you can have a sex life or you may have to move out till she can get her health back on track This relationship is NOT healthy for either of you or the kids.....Listen to your therapist.............
