Date a friend???

So I recently came out to my group that I’m bi (my group is 13 girls and only 4 of them are not homophobic)

and when I came out she was like “me too!”

And I was so happy cause I have a little crush on her.

She texted me that night and told me that she wasn’t ready to come out yet and I told her that its okay and our group’s reaction was much better than I expected and we’d get through it together.

Now about a month later ( this evening ) she texted me asking me out.

Her text goes like this:

“Hey I know we’re just friends but would you like to go out sometime? I totally understand and respect it if you say no.”

Is a relationship a good idea? Especially cause 9/13 of my friends are homophobic af and my entire school is homophobic.

update:

Okay guys I’m not going to just up and leave my friends, I’ve been in this group for 6 years and they’re the most lovely girls ever and I love them all.

And yes we are all Christians in our group but some of them are more strictly so, while 4 of us have different perspectives. I’m not leaving my friends just cause I have a different perspective to them. That’s like saying “you don’t like my favourite colour? Screw you we’re not really friends if we don’t like the same thing.”

The real question I’m asking is:

Will being in a relationship with a friend affect the friendship? Is it risky? And will it be weird to be in a relationship with someone who you’re in the same group as?
