My ex of 5 months dumped me saying he wasn't ready for a relationship. I told him that I had doubts about this relationship so I guess it worked out. I then said it's not like I'll be heartbroken or anything so it's fine. I also blocked him on ig right afterwards. I've now been doing no contact for a little more than 1 week. I'm just wondering if my statement was too cruel and would he never contact me again because of what I said?
