Urges for girls

I'm in a relationship with a guy whom I love. I am also bisexual. I crave women and not anyone specific just to like be with a woman every once in a while and I wanna relieve it but he won't let me. I love him and Dont wanna loose him because I want a life with him. I refuse to cheat. But I Dont know what to do. If he was in my shoes I would let him be with a guy every once in a while if he wanted to ad long as it didn't get out of hand. Should I just ignore my urges?? I can't really though so Idk. Plz no negative comments. I've had enough if that in another group... I hate that I'm bi. But I can't help it...
