A guy I’ve known a while and I have recently started speaking (both 30’s) a lot over WhatsApp after about 3 weeks of messaging regularly every day we met up and ended up sleeping together I found it fine just a bit awkward this was 3 days ago and since then it’s become painfully awkward. He messaged after saying he had a really nice time I was a little distant/slower with my replies as I have a fear of rejection and since then it’s just felt very different. He’d normally double message and the conversation would flow where as now he doesn’t double message but could this be because my responses are less?
