Now On a serious Note:
My advice to all the ladies and men in the chase phase of a relationship is enjoy it, as reality beckons.
For all the ladies in the post-chase phase, you have to add value to your man's life if you want him to value you (and this goes for men too). Just ask yourself what it is that you are bringing into the relationship, beyond pretty face and sex…what else are you good for? This is what counts! Such things as sound and unselfish advice that would benefit him and his future, financial planning advice, care, do you make him feel big or small?
If you do this, he would always want to be around you…and even if his attention strays, I assure you he would be back!
