<human>: I don't know what to do. He's 25. He's a big boy. I'm not his parents. I'm actually very happy and excited for him. But the girlfriend..  oh the girlfriend....

Shes 3 years younger, college drop out, drinks 3-4 nights a week, shes dumb (I mean she has a low IQ. she isn't smart.) She uses him for his money. She hates all of us (his friends,) won't give us the time of day to actually get to know her cause "she has enough friends." They moved in together, at a house he bought, mind you, after dating for about 4 months. This was 4 months ago. So 8 months in, girl is now pregnant. Now he's stuck. At least that is my opinion. 

I'm not worried about my friend. He's a hard working, has earned what he has, and I know he would do anything for a child if he had one. I'm just worried about what this girl is getting him into.
Do I approach him and bring up my concerns? We have known each other for probably..  18 years? Obviously I am going to support whatever he does, as I have a very deep respect for this friend, but I feel like he might be making a mistake at this point in his life.

Can you provide a brief overview of the text?
<bot>: My friend is having a baby with a girl who's a piece of shit and uses him for basically everything, and I don't know if I should support him or bring up my concerns.
