Viviene couldn’t have put it better.
It’s not difficult. Men are fairly simple creatures and if he wants to see you, he’ll see you. You won’t be stressing about deciphering messages because it will be quite simple - and I say that as someone who was in this position for 10 years!!!!!!
You’ve asked him twice and he’s accepted or at least suggested an alternative “can’t do then, but about how about doing x on x?”
I’ve no doubt he likes you and wants to see you. On a casual basis, for sex. Which if you want that, is fine.
But you don’t, you want a relationship and that’s ok. There’s nothing bunny boiler-ish about wanting a stable happy relationship but don’t kid yourself this man is it.
He wants fun by the sound of it, and that’s ok too. He’s just not right for you and what you are looking for. So move on.
Know your worth. Please please don’t hang on, waiting for him to throw you a morsel of attention. You’ll waste so much time doing that and is that all you are worth? Waiting for him to beckon you when he fancies a shag? No!!!!!! Of course not.
Unless you specifically want a bit of no strings fun, please don’t waste any more time with him.
