He should have known better, but some people just have to get burnt.
If we lived in an ideal world where females generally showed gratitude and loyalty to dudes who 'save' them and treated them like kings, it wouldn't be a problem. But history shows that is almost always never the case. Countless examples of dudes getting played despite throwing money and gifts at a broad just because they have a nice smile with a big behind and a sob story, yet they still never learn. Fukk I look splashing out on a chick like Maliah Michel, for example.
(who this dude in the smilie dated at one time).
If anything, the only women you should be showering with money and gifts is your mother and maybe your grandmother if you're lucky enough to have one. Other than that.....
