Bit of a weird question, but I'm wondering about neurolinguistic programming. An abusive ex secretly had a qualification in it. I found out after we'd split up. It's just bothering me that he may have used techniques he'd learnt on me in a negative way. Sorry if it's a daft question, I'm not even sure if it's possible. It's a long time ago now, I'm not in distress from what happened, nothing like that.... just wondering.
Just wondered if anyone knew anything about it really.
