I could be using the term "weak" incorrectly but I'll let y'all decide.

My GF and I haven't gone on many dates recently and I've been looking to change that. I've been slowly adopting some RP tactics and make it a point to not really ask as much as I tell. This is easy to do in person "let's go to --- on Friday" but I have found it impossible to do over text. And I know the answer is "just text her how you say it in person" but I find it hard to do that as well.

So how do I ask my girlfriend on a date without resorting to "would you like to go here" or "how do you feel about joining me for dinner"?
