like I say its hard for anybody to get an insight into a relationship unless you've been in it yourself.
Having been dumped more than a few times, and even having to walk away from a few, breaking attachments and ties is hard for anyone going through it. That's why break ups suck, as few of us can see this as a learning experience, or the opportunity to do something better. Its just to traumatic to see anything but the hurt and misery you are feeling.
Your feelings have been stirred up by your meeting, and talking, and you are finally turning the corner from hope, to acceptance of the changes you are confronted with. That's a good thing, yet for now, still sucks. In time though, it gets better, and after a proper healing, slowly your wounds don't hurt as much.
The key is be willing to let go, and then through NO CONTACT, redirect your energy elsewhere. Building a life that you enjoy, after a proper mourning for the end of the relationship, with family, friends, and activities, will move you forward. The hardest part was getting used to sleeping alone, and waking up alone.
That was a huge adjustment to make, and I highly recommend a fairly strenuous physical activity, done regularly with a proper cool down time, at least 8 hours BEFORE bedtime, and other chores, or activities after. In this way you are tired, but not wired at bedtime. In the end of a week you sleep better, eat better, and feel better, which is important moving forward, and establishing a routine schedule for yourself.
The busier you are in all areas of your own life, the faster you heal, and feel better about YOURSELF. I have found that time flies when you are having fun, so plan plenty of it. That's how I have recovered, and renewed myself, through some really heartbreaking times, and thrived to survive.
Still break ups suck, at first, until you make the right adjustments to cope with your loss. Break ups are a temporary event, and obstacle to be dealt with, and hardly the end of the world, merely the beginning of something better. An attitude adjustment.
