Hi Poppy
You have my every sympathy. But you will be OK. Even though I knew that parting from my Ex-DP was the right thing to do, it still felt at the time very crap, and continues to do so at times even now, a few weeks down the line. So I make sure that I remind myself of the bad times, regularly.
One reason why you feel rotten at the moment is that, as you say, there is a void in your life without your Ex-DP filling it. But, as Hermonie and others have has said, time is the healer here - so just take one day at a time and concentrate on you.
When a non-EA relationship breaks down, if it was any good, we miss that person, but the chances are we will still have strong bonds and regular contact with other people in our lives (friends, family, colleagues) and will still do things that we want to do (hobbies, sports etc) because out non-EA former partner will not have taken over every waking minute of our lives, or trained us to make meeting their needs and wants the focus of our every waking moment.
And that's why when a relationship like the one you have had with your Ex-DP ends, the void can feel enormous and at times, overwhelming. Because he's effectively taken you over, and the bits that he hasn't taken over are all engaged in the 'fight or flight' responses we have to dealing with chronic, ongoing stress.
I personally found talking about the relationship, and its breakdown, with a few close friends, as often as I needed to, very, very helpful at the stage you are at. And company, as often as possible - going out every evening to visit someone, or them visiting me, was crucial in those early days of flying solo.
It will take you time to get to who you want to be - and you may well be right when you suggest you have deeper issues to address that maybe pre-date Ex-DPs arrival in your life, and which, perhaps, made you more susceptible to Ex-DP's unhealthy behaviours. I now know that I do and I am slowly trying to address them. None of it is easy, because if it was, we would have done it before now. Talk to your counsellor about these.
And just let Ex-DP go - try, if you can, to accept that you aren't what he wants - and more importantly than that he isn't what you want either. And he is not going to change.
Put it this way - if you went to a restaurant and ordered a freshly cooked burger, fries, and salad, but you were served with cold, mouldy sago pudding - would you accept it and eat it? I think not.
We can all think and wish, oh if only he'd do this, or say this, or lighten up about this or that. But the reality is that men like your Ex-DP and mine, don't. And we can't change them. No amount of love or giving will satisfy them. And it's not because we aren't good enough. It's because they are emotionally inadequate. Your Ex-DP might seem in his element and sorted right now. So what?
And finally, do try to exercise as much as possible. You may not feel like it at all, but believe you me, every step you walk in sunshine or rain, every yard you run, every length you swim, every ball you hit and every move you dance - it all just helps you to stay that little bit healthier and feel that little bit better.
You can do this. Courage.
