Break Ups and Instagram

Forums

My ex and I broke up a little over a month ago because of distance and I've implemented the no contact rule during that time. Even after we broke up my ex continued to like my instagram posts and he would view my instagram stories. However, it's been over a day since I posted my latest instagram photo and he did not like it. Normally, he would like my photos within an hour or two after it's posted. I also looked at his profile and he deleted all of our photos together. Is this a sign that he has moved on? Is he still hurting from our break up and that's why he deleted our pictures and did not like my photo? Is he trying to get a reaction out of me? Is there no hope for us because I ultimately want to get him back. I'm coming back home in 2 weeks and he knows this.
There's a lot of reasons as to why someone would do that, but in my experience, I see people end to purge their social medias of reminders when they are really hurting. People also tend to cycle through the stages of grief when they are dealing with the end of a relationship. Give him more time to settle his emotions, and then you can casually send him a light-hearted and simple text when you come home. I would never say that there is no hope, but if distance was and is still an issue, that is something you will both have to agree on, and come up with ways to work through. If you need any advice on how to make long distance relationships work out, please feel free to reach out to any of the Experts. (:
Distance was the reason why we broke up. When we broke up he said we can reevaluate the relationship again in January when I get home. But the way he's reacting on Instagram is making me think he might not want to reevaluate the relationship. Thoughts?
