Hi! Forgive the burner.

I've been in a relationship with my boyfriend for two years; it's sincerely great. I'm really happy in the relationship, and he's a sweet, caring partner. We live together and I love our life together. I sincerely do not want to break up.

I do, however, want an open relationship. Not because I'm bored, or because I want a 'soft breakup' - I just want to experience new things and new people, and I want him to be part of it. He's my best friend.

I don't want a second boyfriend - just friends with benefits and a longer leash. I'm happy to extend the same to him (if he meets anybody he wants to fool around with).

However, the one time I tried to bring this up, he cried. He hated the idea that I might ignore him or stop spending time with him. I don't want him to feel like I don't love him or that he's not enough. 

How should I handle this? I'm feeling the urge to cheat in secret rather than hurt his feelings. I just want a hallpass - not to leave someone I love!
<bot>: I want an open relationship, but bringing it up made my boyfriend cry. I love him, he's my best friend, and I'm not interested in breaking up - I just want a hallpass. What to do?
