You should always show him a little bit of attitude. This will give him the impression that you have also moved on and you are a strong person. When he tries to get close to you make sure that you play a little hard to get. This way you will not appear needy and he will realize not to take you for granted. However make sure that you are not playing extremely hard to get as this will only distance him from yourself even more. You should always leave him feeling at the edge.
