I know not a lot of you will ever need this, but still. Sometimes you are attached to someone, and then boom - all is over.

I checked a lot of stories. If you don't block the person completely - you'll suffer forever. But if , say, a girlfriend leaves you - remove all mentions of her from all your digital devices and all the physical contacts too.

I.e. block phone numbers, delete all photos, block everywhere in FB, Twitter, everywhere. Change an appartment, a room, a job, your daily activity - nothing should remind what was before. Tell your friends / relatives that one mention of the person and conversation is over.

2-4 weeks - and a brain can not "confirm" neuron connections, they start to disappear. Make one exception though, i.e. check her FB from anonimous account - boom, you keep your neurons, the shitshow continues, cortisol keeps killing you.

With kids, well, until you get a full custody - it is over. A father once a week or once a month can not participate in raising his kids - thus forget about them. Make new ones if you need to. It is over. Minimize payments and live a new life.
