My Fiancé Left Me Abruptly 20 Days Before Wedding

My (24F) now ex fiancé (24M) ended things between us this week after being together for four years and engaged for 2. We were only 20 days from our wedding when he ended things & I can't help but overthink & feel like an idiot. He keeps saying it's not me, but that he has issues in his own head that he needs to figure out for himself. He wants to be able to go on a random 12hr roadtrip without me questioning it or freaking out. If he wants to take a vacation by himself, he wants to be able to do it & not be questioned. & now he does not want kids— after the last 4 years of being on the same page & him saying things like “I can’t wait to make you a stay at home mom” “when we have kids, I’m going to be the fun parent” “you know I want 2 kids, just like you”

I wanted to be there to support him through what he’s going through & be able to work it out with him be had the truly was the love of my life and my best friend. We just bought a house together last year, so we're both still living in the same house, we bought a truck together that he took with him, & we have 7 dogs together. I feel like my whole is crumbling and coming to an end and I know there is someone out there that can & will give me everything I want, but the thought of moving on is so scary to me because i pictured the rest of my life with this man.

I feel like l've been taken for granted and my kindness was abused. When he wrecked his motorcycle, I slept on the floor by his side for 3 months while he heeled. I left my family & friends behind for him. I changed jobs, sold my car, bought us this house, let him change the wedding plans to accommodate his wants & his family, & he can just end things with the blink of an eye. He keeps telling me he loves me & he even initiated sex when he ended things despite me not wanting to bc it “was his way of showing me he still loves me.”

He still lives in the same house for a moment & selling the house isn’t an option nor is me leaving. He refuses to talk to me about how we can split bills now & how things will work from here on out. & when I asked politely for him to sit & talk with me, he got nasty with me.

I’ve been leaning pretty hard on my 2 best friends, but I don’t want to lean on them so much & smother them. I don’t want to bring them down with my problems & I don’t want to inconvenience them at all.

I feel hurt, used & discarded & I don't know how to move on from this. He keeps saying if he figures it out, we can try again in however long it takes. Like he excepts me to wait for him? Should I wait for him? How do I move on from the future I had planned with him? & more importantly, how do I pick myself up & out of my depressive episode?
