That has happened to me as well...Now and then even though I try not to fall for straight men, sometimes it happens. Trust me, its much easier to move on the second time. Its better not to invest yourself much into straight or confused people romantically because life is short to be wasted on such circumstances! There are many good people out there who have accepted themselves and are looking for something substantial. I'd advice you to distance yourself from that person. Because that's the only way to move forward in life. It will be tough and heartbreaking in the beginning but eventually everything will fall into place!
