Yesterday, I sent a text message to invite a girl who had been on four dates to go out to see a movie at the weekend, and I haven't replied yet! Should I keep sending it to her?

If she doesn't answer you and rule out the accident, don't look for her again. A watched pot never boils. Is it because you asked her out four times and she was empty, or is she in a bad mood and wants to find someone to accompany her? ... going to the movies is a more intimate way to date. If she doesn't like you, of course she will refuse. When you like her and don't know her very well, you can invite her to dinner, drink, chat and call more friends, so the atmosphere will be better. Look at her attitude towards you and get to know her before you go on a date.
