It is good to be a jealous woman but if you do not moderate it, it might lead you to trouble. Men normally like to have freedom and to mingle with friends and colleagues at work. However, if you are the type that acts insecure all the time and you assume that he is cheating on you whenever he is away, your guy will get tired and will eventually leave. A woman who acts insecure is a big turn off. This could have greatly contributed to your break up.
