Multi pronged strategy: 
- When you're around them pay attention to how they treat other people. If they don't treat you any special attention or react any differently to you that's a sign that it's not mutual. 
- Try and do activities with them. If you talk to them and find out what they like, if they like you back they will usually be happy to spend time with you. Activities could be videogames or watching movies or stuff.
