I heard a theory once about this ‘being friends’ thing, and it’s really turned out to be true in my (wide) experience.
You and this guy started as strangers, moved to friends (even if only briefly!) then lovers. If you really want to go back to friends, you have to go through a strangers phase again first. You can’t just go backwards in the cycle.
Get on with your life, let him get on with his. No contact, other than absolutely necessary practical matters. Otherwise, apart from anything, what will you have to talk about oh so casually?? Your relationship is what, and that’s not friendship is it?
Of course you will start to feel better soon. When that happens, maybe have a long look at (with a counsellor?) why you invest soooo much in a man and his feelings for you? Finding a life partner doesn’t need to be this devastating. Somehow or other you need to be responsible for more of your own happiness in life. No other person or pet or child will fill that hole. Certainly no impossible fairytale bloke will.
When heartache (not break, it stays in tact) has come visiting in my life, it has helped me a lot to really concentrate on my sense of dignity. I’ve literally dragged myself off the sofa, into a shower, into clothes and sorted my hair. You are not a broken, wailing animal. You are a proud strong woman who can definitely make adult choices (like staying off her phone). You come from a long line of tough women, who faced worse than this. They are standing behind you now, hands on shoulders, going far back in time. They are all saying ‘You’ve got this, wallowing time is over’.
The phrase ‘Pull yourself together’ is widely used because a) it is a real solution to loads of modern problems, and b) because ‘pull’ implies there’s some effort involved. It’s an effort that will pay off. Promise.
