I need advice

I'm think i might be in love with my friend, I have confirmed she's bi but I'm pretty sure I'm not her type and I'll be so fucking heartbroken if she finds a girlfriend/boyfriend, bc we have so so so much in common and she's the first non straight girl I've ever had a serious cursh on,

Do I distance myself from her beacuse everytime she says something jokingly flirty I'm reading into it and wondering if she likes me too, we talk the most to eachother and touch eachother playfully but I just wanna go a bit further and get a little closer or am I just greedy as hell
