Same reaction you've gotten I'm sure.
I saw the current chick today and we talked for a bit. She said she understands my position and told me that if I want to break it off with her, it's cool. I've told her before that no one will stand inbetween me and the kids and she does respect that.
I spoke with one of my professors about all of this today and she gave me some things to read about sex addictions. She doesn't know of any sex addiction support groups in the area (that's what happens when you live in the middle of nowhere) but pointed me to counselors on campus. Addiction isn't her field of study and any professor in the department that tried to counsel me would need permission first. Go psychology, they'd make a research study about the whole thing.
There is one professor in the department that has a background in addiction counseling and she is going to talk to that professor for me so I don't embarass myself. I'm to get back with her on Friday and she'll let me know if this other professor is able to help.
