Tough love?

To love her is tough... At times she's unkind! For when she gets rough, She whacks my behind! Yes, off her I live.. For that I've no shame! So much do I give... For lots take the blame! Love and affection... Such loyalty too! Watchful protection... Wish more I could do! Guys call, what a bind... I've ten thousand fits! My teeth I do grind... They're simply the pits! Why do I not leave? What for do I stay! For both we would grieve, If one went away! I know she loves me... Get plenty of hugs! But the name Fifi... Hell out of me bugs!
