First of all do not smother him or dog him down. If you really want your man back you want him to miss you and just remember what drives a man crazy is when he can't have what he wants. You have to act like you moved on by showing that you are happy and always look your best in public so he will know that he lost a good catch. In addition you can show up in public with men who are a good catch to show that you are wanted and excel at everything that you do.
Secondly do not get your girlfriends involved because they would make the situation appear a lot worse than it is, and lets be honest who can you really trust.
If he did make an impulsive decision to leave you for another woman he will miss what you two have and realize that you are that much better. If it is that he was cheating on you for a while, sorry honey but he had enough time to decide why he liked her better and worse yet something was lacking in your relationship for him to cheat. If he is known to be a playa honey you don't want him anyway. However if you are married and he cheats, girl you fight for your husband especially if you have kids. You have the right to embarrass that outside woman and expose her and if all else fails god is real and karma will come around just wait and see. I can give you stories of outside women they are never happy.
make him jealous
You don't.
Win the lottery, or have a miraculous experience. Please do not hold your breath .
Depends if he is stuck on that other person still
ignore him and let be seen with a cuter guy.
dont just dump him
You can't trust her anymore. Give up.
Give him a reason and tell him why you did that..
Stay out of it! You had your chance with her and it didn't work, so as long as her boyfriend is still around it's best to move on. If you find you still love her in a few months then the only time you should feel free to try and win her back is when and if she break-ups with her boyfriend. Yes if you have feelings for her you need to at least try to get her back.
Be sexy, try to be hard to get but constantly around him at the same time
