People make time for who they want to make time for. People text, call and reply to people they want to talk to. Never believe anyone who says they’re too busy. If they wanted to be around you, they would.
If you really love someone, even if there was a million reasons to leave, you would still look for the one reason to stay.
If you love someone, set them free. If they come back they're yours; if they don't they never were.
