Why is he ignoring me?

It's possible that he's taking the time to reevaluate his feelings to be sure that he wants to continue seeing you as he was, but it's also possible that he genuinely had something come up and decided that it was in his better interest to not keep you informed. There's really no way of knowing exactly why he stopped talking to you without him telling you exactly what it was. I suggest reaching out on Facebook, if you haven't sent him a large amount of texts already. Or, perhaps give him a call and leave a voicemail making sure he was alright and that you'd be there when he was ready to talk. I've had the same situation happen to me before, and it turned out he had been seeing someone else and she had found out about me. Hopefully it's not the same for you, but you never know. Good luck figuring it out, but whatever happens, just be aware that if he decided to cut off communication, there's no reason for you to go after him further. That, of course, was an "IF". Otherwise, I'm sure he'll answer. He seems nice enough from your description. Good luck. Cheers xo

Patience, you really just need patience. There are way to many options to why he is not replying. I know it's nerve racking but there is nothing that can be done but to wait. I don't suggest you worry so much you ruin everyday life for you. Sometimes a man does need to have time to think over things or just need a little space.
