Sorry you felt the sting of rejection.
If you can get that 'thing' I've been talking about handled, your confidence in your own new-found feelings will come through to whomever you're courting.
Souther noted
IF I were to have...a relationship with a little girl...
See, when you say "a relationship with a little girl" you know and I know that you're using 'relationship' in the adult sense of the term - a 'real' relationship with sexual intimacy, mutuality, equality, sharing of mutually enjoyable adult experiences, and so on. But see, if therapy were working effectively, Souther, you'd know that a real relationship with the qualities mentioned above just cannot happen with a little girl. You wouldn't say it. You'd say: If I assaulted a little girl, or received sexual gratification from her. Or words of that ilk, showing empathy (not sexual equality) with the child.
You also wouldn't focus on a tertiary issue like 'cheating' because the gravity of the child intimate pursuit would impress itself on your mind. And 'cheating' would be the least of your concerns.
Take a break from dating. It can interfere with what you're trying to accomplish in therapy. Or disclose it to your new partners. Either way, concealing it won't be very 'real' or 'adult'.
