If he’s feeling generous, strike while the iron is hot - they only get less generous as time goes on.
As for dropping the rope - do you understand what that means? In a tug of war, you pull on the rope, he pulls harder. You drop the rope, he falls over.
Picture this: he comes home and you look mopey and sad and haven’t done anything interesting. Is this likely to make him attracted to you? No.
Imagine a different scenario: he comes home and finds a couples empty used wine glasses on the back porch and an empty wine bottle in the kitchen . You also have sexy new lingerie drying in the bathroom. Maybe an empty Victoria’s Secret bag in the trash. Or a new hair color/ cut. If he asks, you just had a visit from a “friend”. If he pushes, tell him it’s nobody he knows.
Mind you, I’m not suggesting you date or do anything he could hold against you later. But it doesn’t hurt to let him think what’s good for the gander might also be good for the goose. Oddly, they never think about that possibility at first. Curiosity about what you might be doing while he’s gone might switch his attention from all the fun he’s having, to worrying about all the fun YOU might be having. Sometimes that’s enough to snap them out of the fog.
