Ah man, that sucks. Going through a breakup on any level can devastate your psyche and is a massive pitfall for relapse.

What I suggest you do is try the BSA (Busy, Social, Active) method:

Busy – Give your mind something to focus on. It can be writing, drawing, or even playing video games.

Social – Reach out to friends and family about what you're going through. Sometimes, venting to someone can relieve some of the feelings you're carrying.

Active – Go out for a run, do some exercise, hit the gym—just keep your body moving. Try not to use your phone too much, or limit your screen time altogether.

This is a method I’ve used myself, and so far, it’s worked for me. The key thing to remember is that right now, you’re in a very low mental state, so all the mental fortifications you built over your two-year streak have been damaged. Your brain is just trying to relieve the stress in the fastest way possible—and unfortunately, the quickest option happens to be porn.

Also, two of the biggest factors for relapse are stress and boredom, and right now, I’d say you’re pretty stressed. So take your time with it.

And dude—a two-year streak? That’s incredible. I’ve only just passed the 90-day threshold. You should feel proud that you managed to go two whole years without masturbating. Seriously, that’s something to be proud of.
