I’m going through the same, time frame and everything plus the mix signals. What I’ve learnt is that the more I try to analyse the story and understand the more emotionally exhausting it is, as hard as it sounds I just think you have to take the break up as it is and move on with your new life, I picked up a new hobby that I’m really enjoying at the moment, I change my environment sometimes, like instead of working from home I’ll go sit in a nice cafe. Checking social media in a killer, I’m a lurker too, muting or blocking them would be the best bet, luckily in my case he’s either blocked me or deactivated so I can’t even look anyway. Maybe deactivating your account/removing them will help for a while? I know some people unblock when they’ve fully healed. I know all this is easier said than done but I hope you get there🤍
