Hi Kittie:
There are two issues here: 1) pelvic pain, and 2) your fear of intimacy (very understandable, given your history).
1) Pelvic Pain: this is not a gynecology site. I suggest you post in the gynecology expert forum and detail your medical history. Perhaps the gynecologist will be able to suggest a specialist in pelvic pain. I have seen several women who have experienced such pain from internal scar tissue and other issues.
The gynecology expert forum is at:

2) I want to urge you to continue seeing your therapist, because obviously, this is beginning to help you to get some clarity. Some issues to explore with your therapist are 1) whether you have a history of emotional or physical trauma in your family or in your relationships aside from your ex and 2) whether you've received any messages regarding trust and intimate relationships. There's a reason for your emotional distance and lack of affection. You need to explore what that is. Best of luck to you. Dr. J
