Feel it? Then say it.
Wow not sure how I love you can be over used.
I know that it def can be 'under' used.
I say love you to my boys, my hubby my friends often. If I feel it I'll say it. I agree actions are important too. Without the actions the words are pointless. But without the words..... Would be a sad place.
I think people get scared with the phrase and what responsibilities ( read baggage) comes with it. Then don't say it. Love and all it's stuff can be heady,sweaty hot, cold,painful and ecstatic ! And sometimes at the same time. I love saying I love you to the ones I love. But please don't feel you have to say it back. Tell me when you want to, spontaneously when you feel it. Or don't . Your choice.
