When should i tell her i want to date her?

Well i met this girl, now i talked to her like a month ago, but we stopped talking until about 2 days ago. SO we messaged each other on this site, and lets me just say i’m not sure she feel like i do. but yeah we messaged each other this site, just talk, so on the first night if us talking again i called her and i think it went well ( first time we ever talked over the phone). So the next day i told her i really like her, and she said like she me too ( i dont know in which way), along with just normal convo, and we made plans to hang out this weekend.. but after i told her i really like her, she said we should hang out today..

so first time meeting her face to face, she came over to my house. It’s went better then i expected we was laughing the whole time and stuff, so after that we made plan for Saturday to go bowling , it’s also the day where i’ll get to meet her son ( he about two and i got a daughter too so no big deal)… So i’m stuck between should i tell her now or after we go bowling and see how that go… or just dont tell her at all….. i mean last time which was about a month ago a topic like this came up and she said she wasn’t ready to date but i dont know about now…. i mean i even said we should go on a date one day sorta like a joke, but she said most def.

so what should i do??? Because i like her and not only that my family like her as well.. and i dont know how should i say it, cause i dont think being to blunt would be a good idea

need some serious advice
