If your trying to get a man back that you are in love with then just give it time. If you had a relationship for over 3 years and you just broke up and still have feelings for that person then just give it time. Take that time to get into shape, do something different with your hair, change your appearance all together. Nothin better then a guy seeing his ex girl walk in a market looking better then ever! Trust me i been there.
If you go chasing him then he is just gonna wanna turn you dont cause guys love to be in control, but if you let him find out what he's been missing from his life then he will definately come back to you. Without a doubt!!!
