Should I breakup with GF because son hates her or wait it out?

2 years ago my son (who i didnt know i had before that...long story) came to live with me and we have been through some major stuff and all but are getting things worked out now, i love him, and think things will be cool. problem: I have had gf for about 3 years (we were dating before i found out i had son...) anyways she is very nice to son, always has been and she is willing to wait a while till things settle down more and all (but seems to be pretty impatient now, but doesn't wanna breakup), but my son (15 years old) can not stand her at all. I have talked with him and everything, long story short, not only does he see her as stealing me away from him but he thinks she is a skank, along with all women (his mom situation was very bad). i have tried to talk to him, but he still hates her. Should I break up with gf for my son, or would that be bad, like, too much on him ya know? i dont want him to feel guilty or like its his fault i break up, but i also just really dont think i should keep dating if he really hates her that much. and honestly, our relationship has been crumbling anyways, probably my fault. but anyways, what do you all think?
