Okay baby, let's go back to the start.
You shouldn't doubt yourself for no man, ever. You need someone who will treat you right and who will be interested in you. He doesn't seem interested, and that's fine. Too bad for him, and move on. You have other things to do, to create, to love and to grow with. Ain't no time you're gonna waste on doubting yourself, panicking and stuff. Just be yourself, do your thang, be a cute hoe on your IG, and that's it. The ones destined to change you and to be with you will show up at one point, you just have to wait and take care of yourself.
