Went away for the weekend in March to big city and downloaded Tinder. Matched with someone the day I was leaving. He messaged and said he would like to chat. Moved to WhatsApp and we were chatting on there for a few months. Then I went back to same city in June and met up; we had a regular date in the botanic gardens then met up later for drinks then he came back to mine. Carried on messaging, then I went to visit him this weekend, staying in a hotel. We spent almost 48 hrs together. He was messaging me afterwards till Tuesday, now he has just stopped. I don't know what's happening! I would usually message him in the morning and he would always reply. But when I messaged him on Tuesday AM he just said he's not slept well and his brain wasn't working properly. Yesterday I messaged and he didn't reply at all even though he had read them. Today I messaged and again nothing so far, he hasn't even opened them. At what point do I just cut my losses and block? I'm really cut up about it, more than I would like to admit.
