i have been hanging out with this girl for the past one year and literally havent understood a thing about her. everything that she says, i think might bring me closer to understanding her but it is not so . she is the weirdest person i have met. first of all, we hang out all the time and she feels extreme joy and extreme sadness in a very short period of time. at first, she will be really elated and will be hugging and touching me but the next moment she will be sad and depressed. i am so attracted to her that i spend most of my time with her. on some days, we will have excellent conversations and on some it will feel like i dont even know her anymore. she will take some of my jokes sportingly and the normal ones will just offend her for aome reason. she will hang out with me and leave all her closest friends and even the guys she is attracted to for me on some days but on some, she will just go with random ass strangers whom she doesnt like, leaving me alone. for example, she ws studying with some guys today and said that they were really irritating so she asked me if she could come with me instead but just half an hour into our study session, she just left and went back to those guys again. i went with her and at times, she was really rude and during the rest of the times, she was really pleasant and was trying to make physical contact and stuff. the other weird part is that she approached me at the club when we first met and she does that often, if we go together and seems interested but she has no romantic interests in me, she said and doesnt want to be in a relationship with me. i dont really want to let her go as it seems like she is the woman of my dreams. i have no clue about how to deal with her as she is the one who initiates everything most of the times and i have put in a lot of effort to get this close to her. what should i do bros?
