It goes as fast as you can handle it. Mine feels in retrograde at the moment simply because I had a massive crisis in what I thought was going on in my own mind, I’ve been actively avoiding him (yep I know it sounds dumb - I can’t make this look artificial, he has to chase me) and then of course there’s been my friend’s accident.
In my case the answer is I’m not yet quite ready for him, I have work to do on myself before I am right - he’s not going anywhere (that’s for sure) - it’s going to happen. I can see things are changing with me to order.
He’s figuring in my life and it won’t be platonic or certainly won’t stay that way - not what I’ve seen.
Point is this - they don’t have to do a damned thing to be the objects of your desires it’s always you who has to meet them and surpass their expectations. They have to be under your spell literally and that means getting off your bum and doing the work on yourself.
You may as well occupy yourself until you get your object of desire - I’m going to have to have something to talk with him about.
