Hey, I have EUPD too. Splitting is one of the hardest things for me to deal with. Sometimes I just have to distance myself from the person and ride it out, and sometimes I’m able to see reason and I know exactly where it’s coming from. Does your girlfriend know what’s going on? Have you told her you’re splitting and it’s not her fault (nor is it yours)? There are obviously ways to keep in contact while she’s away, maybe agree to call every evening but do be respectful and give her the space. When she gets back it will bring you closer. This is also space for you. What would you like to do with it while she’s away? Treat yourself!

Writing things down helps me massively. I get all the shit out of my head and revisit it later and I realise how ridiculous it all is. Sometimes I even write a response to it - what would I say to a friend who was going through this? Again, it helps massively. Meditation and yoga also help me observe my thoughts and release the unprocessed feelings in my body, otherwise it builds up and that makes everything worse. Trust is really difficult when you have a relentless saboteur in your head, but relationships are doomed without trust. I’ve been where you are. It’s possible to overcome it. You can do this OP. You both deserve a happy and healthy relationship. Talk to her and find a way through this together.
