<human>: Could you distill the essence of the text into 1-3 sentences?

Hello and thanks for reading. 

I've been dating my girlfriend for almost 2 years and we have great chemistry but lately I've been curious of what it's like with other girls. I've just entered into college and while we're able to still see each other, I see other girls all the time and meet new ones in classes and can't help but wonder what potential they have. 

The thing with my girlfriend is that I'm a little bored of her... but it bothers me that we can't have an intellectual conversation. whenever I bring something up I generally have to always explain it to her rather than have her carry on a conversation. I feel she's a little insecure too with things. Another thing that bothers me is her family... they come off a bit as trashy. Her sister, for example is a total airhead  and when I said something about Africa she replied "African people are disgusting, they don't like to wear shoes" in reference to the poverty on the continent.. Her parents spoil them too, and don't take time to punish improper behavior.  kind of crappy parents.. 

Anyways. What do you think I should do or have any advice?
