I've been texting and video chatting with a guy I met on an online dating site over month ago. We were talking daily, but I haven't heard from him since Friday but texted him once Saturday and didn't get a response. I know it's a holiday weekend and he said his mother back in his home country was sick so I don't want to be the annoying girl who blows up his phone, but I've missed not talking to him for a few days. Should I ask him if he's alright or just wait it out? Am I overthinking things?
