His new girlfriend is accusing me of wrecking their relationship

My ex an i broke up last month.

Apparently he still has a nude pic and several other pics of me. The last time I can even remember sending a nude was probably Valentine’s Day. That day he was out of town and we didn’t spend it together.

I kindly told her we don’t have communication at all and I would not disrespect her relationship. I also told her to ask him instead of me. So she’s said if she were to find out I am home wrecking her relationship then she will expose those pics online.....
