What do I do when he messages saying "love meee"?

So my bf is really independent. He's pretty happy being left to game and stuff. I'm needier than that, but because I love him, I make sure to give him his space while we aren't in person. Most days he eventually messages me saying "baaaby!! Love meee!" and I don't know what he wants me to do to 'love him' when we're not in person. When I message him saying that I want cutesy/sweet stuff of some sort for a few mins to fill up my "love bar" then I'm good and go back to doing my own thing.

I've asked him before what I can do for him while we aren't hanging out to show I love him and he's like "Idk, I'm pretty independent and don't need much. I guess just let me do my own thing..?" So I do that and then I'm lost as to what to do when he messages asking for loves cos I just spent the whole day loving him the way he's said to before..?
