idk if this will be helpful to you, but if you want to move on from someone who is not giving you what you need, you kinda have to decide that you want more for yourself than what this person is willing to give you. if they're able to give you more doesn't matter btw. someone can be completely in love with you and it kinda doesn't matter if you don't feel it. what i'm saying is even if they're just super busy or too shy to initiate seeing each other in person, the notion of them being interested and struggling to show it is less important than how their actions actually come across to you. you don't want to have to figure out how they feel anyway, do you?
