My ex and I were together for 3 months and everything was great. I hadn't seen him for the last 2 weeks because he was going through some difficult issues. I had messaged him asking how he was doing and he said he was sad and he didn't want his chaos to be my chaos. My birthday was last Tuesday and he sent me a text saying happy birthday beautiful. The next day I noticed he completely blocked me on all social media and I'm pretty sure he blocked my phone number. Also, my friend said she saw him on a dating website and he mentioned something about wanting to take things slow. When we first got together he had disappeared for a couple of days and eventually got back to me stating he had very cold feet and he was very afraid of getting hurt. He had mentioned to me that he wasn't even looking for a relationship and then he found me and I was perfect in his mind. He mentioned that he would of always regretted not trying with me. Also, in my opinion I don't think he was over his ex. I gave him a second chance and he really tried to make it up to me. He even asked for me to be his girlfriend. Now, he has just disappeared. I guess it's my fault in a way because I let him back in a second time. Do you think he left without closure because he realized he's not ready for a relationship? This is very hurtful. Why are people this cruel?
