So he's holding the circumstances of how you got together six years ago over your head, as if he wasn't a willing participant but you are a Jezebel?
"His women" 😡
"Getting hit on"
WTactualF?
Does he think that you need to be at home, under his supervision, to avoid the fact that other men who are nothing to do with you might come on to you?
Can you not see how wrong that is? He is holding YOU to account for what OTHER PEOPLE (men) might do, He thinks it is reasonable behaviour to ban you from going out. He feels you going out without him is disrespect.
He has serious problems, & if you stay with him, he will make them yours.
He will continue to police you throughout your engagement, demanding that you sacrifice your personal choices & freedom, or he will pull his blackmail stunt again & threaten the wedding.
If you are unwise enough to marry him, as soon as you are wed his control will ramp up.
If you have children, he will escalate further throughout pregnancy & certainly after it. Consider also his misogyny, & what that means for how he will perceive parenting roles, & expect that you take the lion's share of night wakes, career sacrifice, drudgery & housework.
This default "disrespect" stance of his is a giant red flag for a continued & escalating pattern of control. It is textbook that men who believe you owe them automatic respect & must demonstrate this by curtailing your own freedoms, who believe that you are "his woman", who feel entitled to shame you for sexual behaviours they participated in with you, will become worse not better. It is well documented that abuse will ramp up through all the significant stages of a relationship - cohabitation, engagement, marriage, children.
Can you take some time away with him for a couple of says? Stay with a friend or family, while you think things through?
