The problem is your language. I may understand your question but
not everybody does. If things had happened in the past, u should
ask "do you mind if she had had intercourse with her ex-bf?" And
her ex-bf is not a thing. "The thing is that her ex-bf" means that
'thing' is her ex-bf. Lastly, it is either "she loves" or "she
loved", there's no such word as "she love". Thank you for taking
note. I'm not criticising you, but to help you to improve your
english.
