Oh wow... what a confusing situation, Ziffel. I think it's best to be careful and not jump to conclusions right away. I suppose that anything is possible.
I also want you to know that I understand your fears and your worries. There are times when I can be very prone to being scared that my significant other would fall out of love with me, too. I blame my low self-esteem for that, hehe. I always think I'm a loser. But if you don't take the chance, you could miss out on something really amazing. Everyone deserves to find their special someone... the one they know they can and will be with forever. And I really hope that you will find her one day. I truly believe that she is out there somewhere.
A broken heart is so hard to deal with. But... I do think the best way to handle it may be just to give it some time. Since she did (and still does) mean a lot to you, it's definitely not something where you can just flip the switch and feel 100% again. Try to think about the good things that are in your life right now and the people you know are always there for you. And, through time, I do hope you will feel at least a little bit better... hopefully soon.
Today... I could barely stand to be outside at all. It was freezing! The weather here thinks it's still December.
