Hi blues, thanks for the helpful words it has definitely made me feel better reading them.
Update is I didn't ask her, embarrassed to say my nerve failed me. Got talking a few times during the day but to be honest I fluffed my lines a bit and didn't come across at all how I'd have liked so I didn't take the plunge. She was on her phone a lot and I felt awkward and tripped over myself, couldn't focus my brain to carry the conversation and keep her interested. Annoyed at myself but oh well.
I'm back in with her tomorrow and if I get better vibes and sense a good moment I might will myself to do it. Problem that hurt me though was I saw her talking with another lad in there as well and she even sat with him on her lunch, I won't lie it really stung. When he speaks to her he's capable of doing things I seemingly can't. Gets her laughing and to focus her attention on him. What the nature of their relationship is I don't know, they might be into one another and he's way ahead of me or they could just be good workmates and my paranoia has ran wild because of my insecurities . It has made me feel crappy though, it caused my self-belief to abandon me at a critical moment. Is it worth giving it a go tomorrow and seeing what happens at least or just writing it off to save myself any possible humiliation and focusing elsewhere? My big fear/insecurity is that I'll make a move, get knocked back and become the laughing stock of the work. Or worse, the "awww" figure.
