Straight Friend Playing Around Too Much?

I honestly don’t see how this game can go much longer. You either want to move forward sexually, stop the head games and just be friends or even walk away all together. It’s gone too far to be confused about what eachother thinks. I did this same thing with a neighbor in college for a year and then we graduated and left school. I lost touch and regretted never going further with him. 25 years later it’s my biggest regret.
