So my ex lives in a different country and I'm going there to watch a concert. He got really excited and said he wanted to see me. He offered his help to find a place and he wanted to stay with me. I asked him if he found a place to stay because I need to book my flight soon and he didn't reply... It's been almost 3 days. Should I block him and since I'm friends with his family, should I ask them for help to find a place instead?
