Have I Just Failed At The Dealbreaker?

I went on a date thursday night with a girl that i met online. I’m pretty sure that the date went really well. as we were together for 3 hours and there were no uncomfortable siliences, she paid me lots of compliments, and we even shared a passionate kiss, when i dropped her off. She said that she definetly wants to see me again, but as she’s a single mum with the father not in the picture it is unlikely to be for a couple of weeks and we can go for a nice meal.. i work near her though and we agreed we could meet on my lunch break for coffee before then as she’s free durung school hours, although we didnt arrange an actual day to do so..
i sent a text to her when i goy home, saying that i had a great time with her, and that i thought she was lovely to which she replied the same.
I text her the next day, (yesterday afternoon) just to say hi, and see how her day had gone.. i opened the text by saying ‘hello beuatiful’ which im starting to think may not have been the best move..she has yet to text me back.. in hindsight i think i shouldnt have text and wouldve been better of picking up the phone.. im thinking about trying to call her, but dont want to be seen as to keen (if its not too late for that!) but at the same time i really liked her and got the impression she did me, so dont wanna leave it too long..do you think i should just pick up the phone and call her or wait another day or so if at all?
