I need some relationship advice?

Hello dearest forum dwellers.

I shall keep this simple and to the point, basically the short version. I met a girl that is just amazing we loved each other from the start and it has been going spectacular. Key words here are long distance relationship. ( not too long since it's only like 4 hours away )

POINT IS. It was working very well, but than we were supposed to meet in a couple of weeks. And she suddenly realized that it was going too fast for her and that she wasn't ready. And apparently still has feelings for me, but she is simultaneously confused about her's.

She did came out of a 5 year long relationship a few months before we started "dating". So my question here is. Feeling insecure, scared, pressured and suddenly going numb ( devoid of all feeling). Is that something that is authentic, because i have never seen such a thing transpire.

So if you would be kind enough as to assimilate this situation to me in words i am able to understand. Thank you for listening to this emotionally old man's rant. Should there be any further inquires, they are as always available upon request.

Good day dearest forum dweller,

Thank you for reading.
