I have never split bills with dates. I ask for a separate bill when I order, that way I only pay for what I order. Before I tell the wait staff what I will eat, I say "mine will be on a separate check". You need to speak up in the beginning.

Sometimes I go out with friends or family just to spend time with them at a restaurant I don't like and will just order fries, soup, or side salad. I don't like to waste money on food I don't like. Everyone I eat with will say separate check or the two of us are on one check. It isn't a big deal at all. Restaurants and bars are used to it.

You need to tell your BF how much you make, why keep it a secret? He may have no idea that you are struggling.
