Do you trust a man's love?

I guess it depends on the situation, and the man. "I love you" declared as a drunken slur at the pub is generally not expected to be taken seriously. I believe actions speak louder than words, and so when someone demonstrates to me that they genuinely care for me, the words are just icing on top of the cake.

I am a man and when i say yes, i mean yes. I expect others to trust me

well I do believe or say trust man when they say I love you because man will never say I love you to any women if he doesn't

not always, I think it depends on the kind of person.

Not everytime. you can tell if he is sincere or not. In his own doing, in his actions.
