Girls want what they can't have

Avoid your ex, if she tries to talk to you, just say a few words to her and leave. If she asks you a question just say yes or no... dont start a conversation, never give eye contact...just make her feel like you have no intrest in her. This will make her jealous and make her want you bad. Later on she will start getting more firendly and you can start opening up to her until your back together. remember not all at once, it will take some time.
