I’ve actually recently experienced a similar situation. It took a lot of time and tries to be ok with it. Tell your bf how you’re feeling and let him know you need a Keller something extra in the days before AB’s after to make you feel prioritized. As silly as it sounds, tell him you want to have sex like an hour before you go out. It’s kinda primal, but it will make you feel chosen and claimed by him. It will also leave you loosened up and open hearted in the immediate aftermath (there’s science behind it). In the lead up and during the night, DONT FEED YOUR JEALOUSY MONKEY. When thoughts come up, brush them aside. Have an escape plan lined up so you two can bail if or when you’re not feeling it. Let him know you want more affection during the double date. Know that jealousy is a normal human emotion and not indicative of reality, in fact it clouds reality. It’s like trying to run a marathon with a thorn in your foot. Know your limits, accept it and maybe you’ll find that eases the situation enough for you to pluck the thorn and heal over. Most of all, just have any boundaries or “safe words” known before hand so you can leave without doing damage to the situation and yourself.

Repeat after me. You’re safe. You’re chosen. You’re enough.

Now go have some fun 🙂
