She disappeared on me, should I send this text and move on?

I wrote a facebook status that said "Feeling determined. As one door closes, another one opens :)".

A girl I've been dating text me asking what my status was about, then she tagged me in a funny picture. I told her it was about me having a productive day with job applications, career stuff, etc.

This was Thursday night and I got no response. Sunday morning (today) I texted her something light hearted and funny with a question and 3 hours later, no response.

Should I give her until tomorrow then remove her from Facebook? I was planning to send a third and final response saying "I'll take the hint and I'll leave it here. Had a lot of fun getting to know you but I have to get on with other things. You've got my number if you change your mind. Good luck with the future".

Would that be okay to send before I move on? I'm worried 3 texts might appear needy, but my first one was in reply to hers, my second one was a fresh text two days later and my third one will be a day after that.
