Friends

I’m supposed to ask my friend (who I haven’t talked to in a while) if she would like to come over one of the days we are off school. I recently came out as bi on my Snapchat story. I talked to her earlier today and I told her I would text her tonight. As soon as I got home I texted her asking if she wanted to come over. She saw it within the first few minutes I texted her but she still hasn’t responded 6 hours later. Do you think she is homophobic and doesn’t want to talk to me anymore? What should I do? (Btw I’m in 8th grade and she’s only in 6th)
