<human>: My ex and I were together for two years and recently broke up at the end of December. He found a new girlfriend two weeks later. He continued to contact me over things I had posted to my personal blog. I was simply venting my feelings. Things were messy for a time but we have since made up as friends. 

The other day I contacted him asking for a couple of my things back from his house. He offered to meet me and to have a friendly chat. We ended up talking for close to three hours and he told me he still felt uncomfortable and unhappy about the idea of me being or hooking up with someone else. He acknowledged his hypocrisy though but continued to say that he would want to know who the next person I dated or hooked up with is. He also considers us friends now. 

I know his new girlfriend feels as though we are closer than they are. I jokingly said to him that there was no one I could hook up or be with that he would approve of and he agreed. He also said that he would still feel the same three or four months down the line. He also told me that he would 'have words with' any guy who treated me wrong. 

Basically I don't know how to feel. What he said won't make me hesitate to date or hook up with someone but it feels really wrong that he still feels this way about me yet is with someone else. I don't know how to deal with it and it's messing with my head. I would like some perspective on his headspace and why he said these things to me.
