No respect for freeloaders?

[Speedlimits]

I am starting to have contempt for one of my good friends because he has been freeloading in life. If a person almost never works (ie. earns money) and consistently asks for car rides, food, "favors", should one tend to lose respect for them?

Also if this same person has benefited immensely from you, for example I have given this person the following things:

$500+computer
IPOD
Various clothes
Wallet
paid trips etc.
Not even mentioning the countless free rides,food.

Now all of this was done out of friendship for the person but I am beginning to realize that this "friendship" may have just been a ruse to take advantage of me. The catch is that I am not sure my friend has been "consciously" doing all of these things. My theory is that he has been conditioned his whole life to take advantage of people that it has become second nature, I don't think he realizes the magnitude of it.

My contempt for this person has reached an all time high though, mostly because I am jealous of certain things. He has an amazingly hot, LOYAL, smart and funny girlfriend. He goes to college and repeatedly takes advantage of all of his friends. He never pays for anything, his girlfriend will pay or one of his friends will. He lives with one of his friends and his dad FOR FREE. Yes for free. He doesn't pay a dime and EXPECTS not too. He gets free rides, free money from the government, and he has cheated on his girlfriend.

Yeah so basically I have contempt for people that have things that I feel don't deserve them. I am not going to sabotage his relationship with his girlfriend or friends but I am going to distance myself from him and stop doing him "favors". Would anyone else feel similar to the way I am feeling in this situation?
