I'm sorry to hear about your relationship elephant, here's hoping you get the benefits you need from the YOU time, and that you find a caring doctor :)
secretmission - the main symptoms of endo I had (started at 16yo) were very painful periods and ovulation which progressively got worse over the years. 6 years later mum told me that both she and my grandma had endo, so I had a laparoscopy and they burnt some off. Had another lap last April.
My "IBS-like" symptoms of endo (common for endo) were made far worse after each operation, so this is what I'm currently trying to sort out :)
