Lets face it...the Colombian women couldn't be like their American counterparts because they have not been exposed to the wealth in our nation...however, they have dreams like the rest of us.
You can get "played" just as easily from a Colombian as an American. The advantage we have in going there is time. Time to build a relationship on love and affection with a woman, who...if she was an American, most of us would not have a chance, or a slim chance of getting close to her due to competition for her here in the US.
To me, the smart thing to do is go down be the man you are, show your good qualities and friendship. We have been conditioned here in the states that to women here, we are what we provide, not who we are. If you don't want to be played for what you have, minimize what you make and what you own. The women after money will not be interested.
You will have to provide, and you will be sending money to her family, accept that now. But it won't be anything like the money you would have to spend on material things for an American woman. Plus, you will get satisfaction from helping those in need, especially for the one you love.
