"There are times when you realize you miss someone so much more than you thought"

I thought I was making progress and 'continuing on'...But last night I realized how much I actually miss her. Operation DEEP had an activity upstairs in RPCC and HKSA had one downstairs...there was both a literal and metaphysical wall between us... I bumped into her when I went down to get food, we stopped and said 'hi' before moving on. It was so...brief. Does she still feel something for me anymore? I miss her so much, so much more than I originally thought. I feel completely different when I'm around her - happier, more fulfilled... something like that. She's been sad today...something is wrong, something is bothering her. I don't like seeing her sad, it makes me sad too. I wish I could do something for her but I can't... I feel so helpless. It hurts even more knowing that she needs someone to help her through whatever she's feeling and that I can't be that someone. I'm here for her, I told her that. I'm always here.
