Self Torture
You keep checking her TikTok, and you see images of her very pretty and in beautiful locations and you can't help but think that she is with someone else. She ignores your messages for HOURS and don't even bother to reply. The only time she messages first is when she needs something from you. Stop torturing yourself. She is not coming back. She only wants you because you are useful to her -- to help her affidavit, to receive money. If you weren't useful, she would have ignored you a long time ago.
