I firmly believe throwing a ton of money into it, is a bad idea. Get her some gifts act thoughtful. You know like she's your girl. If you want to not shell out cash . However throwing money then taking away seems like a bad idea. Now getting her jealous is a great way to keep her interested. Girls want what other girls want. If you had a real gf or do and she's fly. Leave up a pic, so somehow she can see. Girls love fucking dudes who have a pretty gf.
