Just because you were in a previous relationship dosnt automatically mean she's lost her virginity. If thats the case you should be up front with the potential spouse about seeing someone (they most likely spoke/been with gabdo too) i'd personally keep certain things private such us the person name plus lenth of time together. I have this motto where a man hasnt given you shit until hes spoken to your dad but not everyone has good self control so allahu calam! Not sure what advice to give if you've lost your virginity islamically your not supposed to expose your sin ...very sticky situation dont give away something you cant get back very simple!!
