Best friend/brother

My best friend is four years older then me and like a brother to me, I even call him big brother. We have a lot of memories even though we only met this year. He drives me home sometimes accept when we almost got caught. Anyway that’s not the point, the point is I might like him. I know that it’s a big age difference but he seems to flirt with me a bit. He treats me well and that’s all I care about. I am used to being hit because of some old ex’s. I don’t know I just really love him, even if it is in a brother/sister way. 🥰
