I heard of the story of a married woman who says she and her lover are having silent video calls with sign language because she can't bear not to see him.
Even though they can't hear each other's voices, the lover rests assured that they are missed.
One co-ordinated shopping for essentials with her lover so they would be in the shop at the same time. Yes, they can't kiss, but that slight brushing of hands as you walk down the aisle or catching a whiff of each other's scent will go a long way.
Go to the toilet, a lot! Make up a story about an upset tummy or something. In the toilet you can let yourself be flattered by your lover and wear your smile without worrying about giving it away. Or even send and receive nudes.
Do you have a garden? Guess who loves gardening now? You! Best way to sneak in those voice notes and let baby know you are thinking of him or her.
Of course, if you have money the tips above are cute for a bhozza like you, just send those e-wallets and keep the love burning.
All these tips come from my active imagination and are not a representation of what has happened in my life.
