Yeah I agree with everyone else. I think you’d be safe sending her one more message in a few days telling her you had a nice time and asking her out on a date, but I wouldn’t expect much of it.
@Kate, I think this LW is in the UK. **Everybody** there uses WhatsApp. Even if she didn’t give him her contact info (and I think you have to have someone’s # to find them on there?) she’s definitely seen the message. Source: I have a zillion friends in the UK + use WhatApp daily.
So we met up again and spent the night together, nice girl but she puts on a front and has a guard up, enjoying just Getting to know her a bit more with no expectation at the moment, nice change from always being with the lads on a night out.
