Hello, welcome on the forum and congrats on your new buns!
It’s a very normal behaviour, they not only have to settle in their new territory (new smells, new noises, etc) but also have to get used to their new humans

Don’t try to rush it and be very patient. Keep spending time in the room, possibly on the floor, just reading or using your pc/mobile, or quietly chatting with your boyfriend. Keep offering them food while you’re chilling with them. They’ll get used to you, the sound of your voice, your smell and gradually accept you guys as a part of their territory. 

How much time will it take depends much on their past (were they abused, for example?) and on their personalities. It can be slow or it can be that once they’re comfortable they’ll open up. Patience is key

Hi! I agree that they just need more time to settle in . Luna used to be jumpy at first when I would walk in the room, so I would announce my presence to her before entering until she got more comfortable.

I’ve had one of my bunnies for over a year now, (since she was 10 weeks old) and still sometimes she’ll run away like crazy if I stand up too quickly, or forget to say hello when I’m walking into the room.

Rabbits are by nature shy animals. It sounds like you’re doing all the right things to bond with them. They’ll surprise you one day by taking a sudden leap in trust!

My little Peanut took months to enjoy being pet. Now he’s the most affectionate out of him and Buttercup. Just keep being patient

Both of mine will still dart if I make a sudden jumpy movement or noise, although not as much as when they were younger. I think it’s something all bunnies will do to some extent. As prey animals, it’s better for their survival to dash and then check the surroundings and see that they’re safe rather than having a look first. And don’t worry that they’ve only licked you once or twice. Mine have licked me once and never again and I’ve had them over a year
