Hiya, y'alright?

Pete came into work.
I didn't even notice him at first cos it was busy, and I was running round like a headless chicken, and he was standing being served at checkouts when I went to go on the till, and I was serving someone else when he just said 'Hello Kate', and I just said in my really cheery talking to customers voice...'Hiya y'alright?'.
And then I turned round and saw who it was, and the bottom dropped out of my world for a second.
He just looked at me sadly and walked away while I stood there with my hand over my mouth and tears in my eyes, and then went off and had a good cry in the toilets.
Will saw me crying tho. I hate being weak and female in front of the people I'm supposed to be supervising, but he was really nice and gave me a hug.
Strangely enough once the shock had worn off I missed Pete even more than I had been doing. He looked small and alone, and he texted me to apologise for not staying and talking but I looked busy, and I told him off for coming in the shop in the first place and making me cry, and he said he was sorry and he just wanted to see me. And now I feel worse than ever, and I love him and I miss him, and I want to tell him that but I don't know if it's a knee jerk reaction to seeing him all suddenly like that. Joey said Don't do anything for 2 weeks, let my head clear a bit before making any descisions, but this week has been a lifetime. I can't do another week like this.
