trust issues

if anyone could give me advice on this it would help alot but im talking to a boy & he's very insecure about himself & has major major trust issues & I understand how he is but he is having family problems & he said he loves me & doesnt wanna be im a relationship right now I understand that. but he doesnt wanna open up to me & get hurt & he has trust issues. & I recently told him i was FORCED to have sex with my ex boyfriend. yes it was true i told him the truth & he keeps thinking about what im asking is how would you guys make a boy trust you more? what would i have to do? & what do i tell him about the whole thing that happen w/ my ex ? :\\ i tell him im not like that & never was .
