Why is it as though he’s ghosting me but leaves our pictures up on instagram?

Long story short boyfriend all of a sudden feels lost and stuck in life. We’ve been together 2 years, lived together until recently. Now he’s uncertain.. “are we right for each other?” “I feel like if I let you go, it will be a big mistake” I said I would give him space to figure it out. He said okay.. I replied and he didn’t read it until the following day, never responded. I can respect the space. I thought long and hard myself about the relationship. I came to the conclusion that if a man isn’t certain about me.. then he’s not meant for me. Not after 2 years and living together and even trying to attempt to conceive. We broke up 4 months ago and got back together. He didn’t have any explanation for it and kept contact with me regardless. I sent the text that I thought about everything and felt maybe we aren’t meant for each other. That the anxiety I get from his indecisiveness wasn’t good for me (he gets distant randomly and for long periods ever since we got back together)
It was left on delivered, he’s kept my pics up on instagram. No updates. Is he ghosting? Is he depressed? What is going on? Why keep our pictures up? He took them off the last time he broke it off so it doesn’t make sense to me. Anyone go through this? What causes distance suddenly, and uncertainty? Why would he feel stuck and lost in life and unsure?
