As time passes it seems to get harder, why and how can I move on?

I was in a friends with benefits situation with him for 6 months & I knew him for what would've been 1 year soon. We were mostly long distance, he wanted a relationship but i knew ldr wasn't for me but we both liked each other & long story short we stayed as friends with benefits, although we spoke almost every day.. Well he abruptly stopped talking to me about a month & a half ago.. like dropped from the face of the earth mid conversation one night and I haven't heard from him since. He'd ghosted me in the beginning when we were just hook up buddies &he had told me before he was going through somethings that ended up escalating & well he had valid reasons that I could understand, especially given our nature at the time...
It's been a month & a half, yet as time keeps passing the worse I feel. I reached out once but after 2 weeks, I kept it pushing & just doing my thing.. This past week though something clicked & I've really been feeling hurt.. & I folded & sent him a paragraph.. & I can't help but feel silly, guilty & sad & mad & missong him, like I'm going through all the stages of grief now... when I thought I was handling it all very well.
