Was in a 10 year ltr... Over a year ago I was dumped for an older woman... :( was devastated tbh... We had a house together, pet cats that I adore but couldn't take to a rented place...joint friends, joint plans, all the usual stuff... and then one day it's all gone up in smoke.. & I feel adrift, and I have to give up my home, and I have to get it together somehow.. Figure out how to fix boilers & bleed radiators and do all the stuff he was good at & I wasn't used to worrying about ... luckily Google knows everything!
since then I've felt in turns angry, sad, hopeless, and also.. relieved, free, hopeful... I got out there, learned new things, met new people, started doing all the things I used to enjoy - adventure stuff, hiking, snowboarding in my case, stuff that my ex wasn't so much into and we didn't do together... At first I'd have to make myself get out there... Going to things on your own takes a bit of effort.. When you don't really feel like it.. I'd book up a schedule of things a couple of weeks ahead.. And then I'd find I was having fun.. to my surprise... It used to feel like he was camping out in my head and things would always keep reminding me of him... But after a while it got less.. One day I realised I hadn't thought about him for a whole day.. It gets less... and now sometimes when I do think of him I smile and the memory is more sweet than bitter.. I'm enjoying having my own place again, being as untidy as I want.. Ex was a bit ocd... :) started dating a bit too. Nothing too serious yet but I've met some nice people and had some enjoyable evenings... Key thing was to accept it was over and let him go in peace... For myself - more than for him. Some people just don't work out long term.. You grow, and sometimes that means you grow apart.. I don't want to let bitterness poison my new relationships...
Good luck.. You'll be ok :)
