Trust is earned over time. I assume that you did not tell your husband every detail of your life on the first date. Your therapist has earned some trust, or else you would not have disclosed what you have until now. But I would suggest that you stay in therapy because (a) healing is a very long journey, maybe a lifetime one and (b) the more you talk about the traumas, the more you will heal. That's why I enjoy this forum so much.
If therapy is working and you can afford it financially, stay.
