I'm with you Simon.
I've been there and I know how bad you hurt, and right now you're probably getting all the same old cliche's:
"There are plenty of fish in the sea"
or "It is better to have loved and lost than to never have loved at all"
or "You'll be better off"
When will people learn that comments like that just don't help.
Remember, love is a vast entity, and it can be shared with as many people as you choose, and you will have different depths of love for each of these individuals. She's the one that knows you, the one that understands you, the one you can connect with.....right? It is not easy to open your heart to someone, and once you do you want to keep that person in there forever, and you still can just in a different capacity than before. It seems that the split was amicable, she may be having some of the same feelings, you must support eachother. Also, lean on others- they won't mind as much as you think.
Trust me, you will be in love again, and it will be deeper, and more beutiful than you could have ever imagined- I am living proof.
There is no Fast Forward button for life, and the best way to deal with adversity is to meet it head on. You will learn to deal, you will learn to cope, and you'll see that as the days, weeks, and months pass you'll see that hurt becomes less and less. Ultimately the hurt and pain will be replaced with admiration and appreciation. Yes, down the road you'll actually appreciate this situation for making you stronger, and for giving a point of reference regarding the direction in which you want future relationships to go. But for now you deal. It's not easy, but you're not alone. Talk it out.
I too have made some significant moves in the past six months leaving behind family, friends, and my career to move from Northeastern PA to Wilmington, Delaware. Not an easy trasition. I am getting the same feelings. Apprehension, feeling alone, overwhelmingly sad. I try to keep myself busy, and I am considering seeking counseling- ever think about it? That is why I turned to this site, to gain perspective, and I think that's why you did too. I look forward to an update- If you talk, I'll listen.
