Floralies,
I would try my best if I were you, to resist those urges to text this man or contact him in any way until after you speak with your psychiatrist. You didn't mention anything about your husband knowing or your relationship with him but I wouldn't "rock that boat" anymore right now if I were you. I'm no therapist but I am in a relationship (live with him) and am divorced twice. I have ADD, and anxiety issues, but I also get manic episodes, though not extreme. You mentioned meds. That would be a first step, along with your psychiatrist/therapist, to deal with these feelings. Again I don't know your marital situation, but you did mention this "other man" judging you as a "nutbar". Maybe your marriage is worth saving? I'm just wondering if your husband judges you in such a way. Best of luck to you, and try and be patient.
