Has anyone been or is an a relationship with a sex addict with narcissistic tendencies?

Just reaching out to people who have either gone through this or are going through this. I just recently realized that my partner of 8 years fulfills these and bipolar as well (oh what an education will teach you). For a long time I thought the infedility was my fault, thought I could fix it, but after a lot of learning, a lot of research and a lot of reading, I realized hey, its not me. I'm just interested in talking with others who like I said are or have gone through this. Be nice to support one another - I'm planning on making a break for it before I dwindle more time away.
