Possible trigger: brief mention of csa and family violence

Okay, so this is a little complicated. But if you could bare with me, I'd love some opinions on what to do.

I have been seeing my t for around 2 years now. I am now also involved in a support group facilitated by my t and her colleague. At the end of the first group, one of the group members offered me a lift home. She has given me a lift home the last few weeks and we have a strong connection. We arranged to catch up outside of group one day, I spoke with my t beforehand and she said that if it was a problem they would have mentioned it at the beginning of the group and that if we choose to meet outside group it's no one elses concern. So we caught up for a drink, it was a great day - deep conversation and a really validating experience. However, she told me that her t (the other facilitator of the group) had indicated that 'making friends' wasn't part of the group.

And now it gets really complicated!

I always thought she was cute, but I knew she had a partner so didn't think much of it. Amyway, while we were out, she told me that she had something to tell me, that she'd been holding it in all week and wanted to get it out.

She's attracted to me. I'm attracted to her.

We are both survivors of childhood sexual abuse and family violence, and neither of us are sexually active. I have a lot of fear around sex, intimacy, trust, relationships etc. She faces similar issues.

Nothing has happened between us, just a clear conversation around how we feel and that nothing could happen at the moment.

The question I have is do I talk to my t about this? I'm feeling so overwhelmed and confused at the moment. Relationships and attraction freak me out and, on top of that it's such a tricky situation to be in. If my t was not the facilitator of the group, I would absolutely talk about what's happened and about all the fears that have been triggered in me. But I am scared that if I talk to her that would cause problems with group.

Would you talk to your t? How open would you be? Does it affect group?
