The first thing you have to do is get your emotions under control and lay out a plan. If you start calling him and begging him to stop dating her, it will only make the other woman more attractive to him. Even if you were successful in getting rid of this woman by bad mouthing her, he might start dating someone else. Appearing jealous will only make him want to date other women to get under your skin.
When you bad mouth a woman he is dating, your ex knows you are still in love with him. In order to get your ex back, you have to take love out of the picture. You have to become his best friend and the one he can come to when he is troubled. Think of your best girlfriend and how you feel you can tell her your innermost secrets and she will understand. That is the way you want your ex boyfriend to feel and know that that you understand.
To get started being his friend, you have be able to gain his confidence. That can only come from communication. If you send him a text, he might not answer and if you call, he might see your number on his I. D. and not answer the phone. So, you have to see him face to face. That should not be a big problem because you know his habits and where he hangs out.
If he hangs out at the mall, that would be a good place to run into him and make it look accidental. Be upbeat and tell him how good he is looking. Then casually mention seeing him with a good looking gal and tell him you are happy for him and hope it works out. As you leave tell him that if he ever needs to talk to someone, he has your phone number.
The chances are that the relationship in which he is involved is a rebound romance and won't last. Since you have invited him to call you, when the romance blows up, you might be the first one he thinks of to call. Be sympathetic, but don't take sides. In fact you must let him do most of the talking and you be a good listener. Remember you are being his safety net, you want to catch him and minimize his bruises, but you can't put him back on his feet.
If he says he needs to see you, accept his invitation to have coffee or lunch, but do not go on a romantic date just yet. You cannot appear eager to become his girlfriend again. Let him confide in you as he would a best friend. In doing this, you will be laying the foundation for a long and trusting life with him.
