How would you revive a dead conversation or girls who get cold feet before meeting you for a date?

I do not use dating apps but moved back home. During winter it is full of snow and minus weather, so day game is not an option, so I fired Hinge.

The first time I downloaded it, it felt like people somehow knew I was new to the city because after six months I saw the same faces hahaha. I got plenty of matches but deleted the app once a month. Plus I could not date anybody with a pet, allergic as fuck, anyway.

I usually switch to WhatsApp then set up a date. I looked at my old chats; there are a few dead conversations where the girl did not respond or purely ignored me.

Girls have plenty of options anyway.

I have plenty of abundance, so I move to the next target. I feel I would like to make an experiment to see if I could revive one from the ashes, like in a month when the weather is better to hang out.

I am open for suggestions but mostly would like to know about your experience. Please share, I bet there are a few in my situation.
