There was this guy I was talking to for the past few days on Tinder. We just switched over to texting. He sent me a good morning message, everytime I text him, he replies asap until evening. Literally, our last messages were about him asking about the event I went to, how he just woke up, and what games he likes to play. Him also telling me what he is looking for on Tinder because I asked. A few hours later, I try to message him back with pictures of the event I attended. But literally all of my messages has went "undelivered" to his android sms msgs. I have an iphone. I am so confuse... if I should just message him on Tinder that I was unable to text him? He hasn't unmatched me. Do you think I am block? What should I do?
