Yes. It happened to me, and I have a therapist who said “you’re actually right on track.” My relationship wasn’t as long as yours, and now, 4 years after he pulled his crap, I am beginning to feel peace and healing.
i don’t know if this will help you, but it helped me: my therapist said that it is a formula they’ve come up with among grief counselors that it takes about Half the length of time you were together, to begin to feel distanced from it and heal.
so no beating yourself up, okay? And I know grief sucks, but you can take breaks from it and find things that help you focus on your new life. Another thing I was taught that doing new, exciting things (like going to learn ballroom dance. Or taking a boxing class. Or anything new! Painting!) can give our bodies those hormones that lift us up, and can help us gain connection to new life without that person.
if you’re ruminating about what he did (as, who wouldn’t be?!) a therapist can help a lot with that.
going on a strict diet of not looking at his social media helps, too. It was VERY hard for me at first, and I slipped up a few times, as my ex had immediately married into a flashy new lifestyle, and it was difficult to not get into grim looking at his photos, but I was torturing myself.
now, a few years on, his quick marriage has crashed and burned spectacularly- and oddly enough, when karma* finally came back around, I find that I don’t care, other than feeling sorry for the woman he married.
- my definition of karma: that we live out the energy we live in. It’s just physics, to me - we attract what we resonate. I don’t see karma as my own personal revenge hit-man (oh, I have wished it to be!) but that he lived his life in dishonesty, manipulation, and just constant bad energy, so that is what eventually showed up in his life. In truly spectacular fashion, really.
