I meet a guy from dating app and we started talking and I can feel that we have a great connection, and I feel attracted to him. But I call things off because of the age difference between me and him ( I know that sounds silly but it's my value and dating boundaries I have for myself) and then we both talk about the issue, he wish me good look for the future and i state the same then I blocked him because I know we wouldn't talk anymore. But it's been more than 4 weeks since i block him than today i received a text from a number I do not recognize and i ask the person who is it? Which the person responded it's him. I was really surprised and he text me from another number what's that mean? Can you spot what his motived, what should I do. Is there any advice and also when a guy do that what's that mean.
