<human>: Can you condense the text into a few key points?

How do my boyfriend [17] and I [17] deal with the multitude of girls that seem to cling onto him? We've been dating for nearly 7 months, but it seems like he's accumulating a growing list of girls that could care less that I exist. He's a kindhearted person and sometimes he's oblivious about how some of the things he says can be taken (like trying to reassure a girl that she's pretty to build her self-esteem but not actually hitting on her). He feels like it's his duty to help every person that opens up to him and not surprisingly a large amount of girls often try to take advantage of him this way. Any advice on how to get these persistent girls to stop trying to weasel their way into his life would be greatly appreciated.
<bot>: What do you guys think my boyfriend and I should do to get rid of clingy girls that refuse to let go of their crushes?
