>>7679434 bro. Been through the exact same scenario last december.
We were about to hit the 5 year mark (2 weeks to be precise) and for reasons not worth mentioning, I ended it. Felt very sad and lonely for the first 2 months, then things started to get better and I'm at 90% now.
Don't stay in a relationship that doesn't work or makes you unhappy. It's gonna be a bit tough, but you will go through it and will overcome it.
I will upload a couple comfy papes
Stay strong! cheers.
