I just watch the entire dnp reaction to heated rivalry and there's a new upload, when I get home from work, life is worth livinggggg

so this might be a little personal but I need some advice. For the longest time I thought I was aromantic asexual with no interest with perusing a relationship but yesterday my best friend told me that she likes me (romantically). I really like her too. She is the only person that I feel like myself and that I can talk too but I don't know if I have any romantic feelings towards her or that I'm even capable of feeling. But at the same time I want to try to have a relationship with someone but at the same I'm sooo scared. I really don't want to ruin our friendship. I don't know what to do.
