Girl Crush

I've been crushing on this girl for about a year now. We're friends but we never really text or anything. We have a snapchat streak and see each other once or twice every week. I really really like her. I want to get closer to her but she's very very reserved.

I know she's bi, anyone have any tips on how I could get closer to her ¿? I've never been in a relationship before at all. i just don't want to end up accidentally pushing her away. If she doesn't end up liking me back I still want to be her friend.
