Am I Bi

I met a girl on internet and we started talking on WhatsApp. She was younger than me. I was talking with her bc we shared the same hobbies. We talked for 1 year almost everyday. I liked teasing her and all. But then i became busy and stopped talking with her. And yesterday i met a girl who looks so much like her and when i talk to her my heart is beating bc she reminds me of her.And i find myself thinking about her sometimes.Does that mean I liked her but I didnt realize it? Does that make me bi? Im a girl btw
