Being in love with two women?

Okay I'm in a crazy love triangle with two women. I been with my girlfriend for 7 years and i love her but the last 6 years have been nothing but drama, cheating, fights, and non stop arguing. Now the other woman I known for about 2 years, and she's means the world to me, makes me laugh, share my interests, and thrive for greatness. I always hear the saying that the gr not always greener on the other side. But I figure why not enjoy the view and admire the up keep for the property, lol. But on a serious note, I really believe I should be with the other woman, and start over with someone who's have a positive out look on the world and focus on what is important. What you all think?
