Feeling Stuck, Betrayed, and Completely Lost

Life has been incredibly unfair to me lately. I was betrayed and used by someone I trusted, and now he’s out there happy, living his life like nothing ever happened. Meanwhile, I’m left with the aftermath—confusion, frustration, and this unbearable feeling that I was just a stepping stone for him. The worst part? I can’t even fully blame him because, somehow, I keep blaming myself for letting it happen. And that just makes it all so much worse. I belong to the art field, and the financial instability is hitting me hard. I was working with this guy, but not anymore, and honestly, seeing him move on so effortlessly while I struggle is beyond frustrating. How do men do this? Just switch off and move on like nothing ever mattered? I don’t get it. On top of it all, I feel completely lost. Should I take a break for a while to clear my head, or should I just keep pushing forward, hoping things will eventually make sense? I don’t know what the right move is, and I feel like life just… doesn’t make any sense right now. I’d really appreciate any advice from anyone who’s been through something similar. How do you deal with this kind of emotional and financial mess?
