Hi Jemma & welcome to the group.
Willow has given you sound advice & the only thing I might add is to give this a little time & lots of thought as what matters most may be your friendship with this girl. From friendships, wonderful relationships grow, but sadly sometimes a relationship can damage a friendship too. It's never our intention, it just can happen.I wish you all the best,hun. Let us know how you get on,what you decide to do. Look into your heart, but listen to your head too.
Pooks.
