I'm a Taurus and #1 never cheated on anyone. I generally like Cap men, but they can be serious markers. He isnt too busy for what he cares about. He just isnt that into you. I was with 3 Cap men and while they stayed close and made an effort 2 had some serious demons that required professional help and the 1 was way too boring lol. I'm still friends with the boring one. Hes super smart and funny although a bit sedentary.
Dont make excuses for a man and his interests. If you're one of them he wont allow for you to think otherwise unless hes willing to lose your interest and that means he isnt THAT interested.
