Married and not dating right having sex

So I’ve been telling my husband for two almost 3 years that I want us to go in dates and spend time together without our son and since our son was born we’ve maybe gone on 4 dates alone and that included our marriage anniversary

So back my September I told him I bought lingerie and u would only put it on when he took me on a date that (He planned not me).... I’m still waiting and to top it all off we stopped having sex like it’s been twice in the past 3 months. Like I even had to buy a new vibrator and of course he knows about it. Idk what to do I’ve told him how I feel.

but no what?

Do you date in your marriage?

do you still have sex?

What would you do
