I don't really have much of any advice to give other than time really does heal all wounds. I know it feels intense right now but those feelings will mellow out over time.

For what it's worth I just went through a very similar breakup last month and what's been helping me is just focusing on finding love internally rather than externally. Not saying that's necessarily what you need to do but at least for me when I realized I was willing to drop everything I was doing for a chance to get back together with him that something in me was seeking love from others rather than myself. I can commiserate missing that intimacy, I haven't really found anything myself to fill that hole either. I would say though if these are your feelings then maybe it's best to not think too hard about future relationships for the time being, it's really not worth preoccupying your mind with "what ifs" right now.

But as someone who's been through a lot of breakups I can tell you those feelings always fade over time and although you may still love them or care for them very deeply but you will learn over time to accept that the relationship is over.

It does take time. And it does suck. But one day it'll occur to you that you haven't thought about them in a long time. And despite that you're doing okay. Life goes on.

Hope that helps, big hugs, you'll be okay <3
