i dont think the only problem they have is that you brought him to your house. THAT fact made it even worse. not only did you cheat on your BF, you had had the audacity to bring it into his (and your) home. i can understand couples feeling "bored" sometimes. but looking outside of the relationship won't make matters better. if you really feel this way, let your BF know. if you two can't come up with some kind of solution, then it's probably time for both of you to move on.
