I met a guy on tinder, we chatted well, went on a date, he stayed at mine, I texted him and he's replying but not furthering the conversation, we didn't set another date. Should I text him and explicitly ask? (wording appreciated)

If you're genuinely interested in him and having another date, then yes, I would be clear and ask the question. Then, you've done all you can and the ball is in his court. Before you do that, though, be sure of the way you're feeling. Make sure that you're not overreacting, maybe get a friend to help you and see if it's you or him. If that makes sense... Good luck! X
