The longer you’ve been together, the harder it is to cope with a breakup. The key is to distract yourself until your emotions settle, and do things that move you forward.
Have you ever had to cope with a breakup?
Unless you’re a virgin, or you’ve never had a girlfriend, then you know that no matter which side you’re on, breaking up is never pleasant. At the worst, it’s highly traumatic; at best, it's an uncomfortable chore.
Even if you don’t really like the person that much, you probably liked them enough to have sex at least once. This means there’s a certain degree of trust and a shared experience (sex). If you’ve slept together many times, then emotional bonds exist, like it or not.
Even when a breakup is a good thing for you in the long term, the process still sucks donkey balls. Humans are wired to have empathy. If you see someone bleed, you feel yourself bleed; if you see someone laughing or crying, you laugh or cry with them. We feel what other people feel. These are mirror neurons at work.
Breakups hurt no matter what.
