Do you require your husband/wife to always ask your permission every time he goes out with friends esp when an ex-gf is in that circle too?

i dont ask for permission but i will ask if hes okay with it because its important for me to acknowledge his feelings and especially if an ex partner is going to be around, i think its important that i take a step back and not go before even asking him. usually if i'm meeting a friend/s of the opposite sex, i will let him know then ask if hes okay with it. but if an ex partner is going to be there, i will take the initiative to turn down the meeting.
