feeling lost and exposed

i just got out of a long term relationship and everything feels so different now. i thought we were gonna be together forever but she left me for someone else it was sudden and shocking. i feel like i dont know who i am without her. we used to do all these things together and now its just me and my empty apartment. the sex stuff though, we had some intense moments that kinda got lost when we split up. one time she surprised me with a naughty roleplay thing, blindfolded me and tied me up while she explored my body in ways i never expected. it felt so freeing to let go like that but now im just left wondering if anyone else can make me feel like that again.
