When you get to the point that you're not enjoying it, that's the best time to either re-evaluate the roleplay, or move on. 

(It's a bit hard to understand what's happening since you've fluffed up the explanation a bit)

[quote]I simply went along with their request, after all I hit them up and it's rude to act like any different (At least this is how I feel). But it's getting way out of control where I feel like its not going to work out. It's like they want to rush it, or half ass everything and start really fast, where i like to ease my way in and then pick up the pace. [/quote]

This was your mistake. You have the choice to decline the request, but you didn't. By accepting you don't really have a leg to stand on if you want to complain about it. You say that they are moving too fast but could it be that you, perhaps, are moving too slow? They have an idea and maybe the personal ideas you are presenting are rocking the foundations of their idea.

Without us knowing what's "actually" going on... could you inadvertently be annoying them and that's why they are getting frustrated and snappy?
