Would a guy ever say I love you if he did not mean it?

i think that a guy would never say so as he also is a human and he too has feelings for whom he love

Ya, most definitely...He knows it's a weakness of any girl...

You may think I'm lying, but no I would not say that. it might slip out if I'm drunk, but if I'm clean, there's no way I would say it without meaning it.

Yes. If he is drunk, or just joking around.

Yes...sex is a perfect example.

yes he definitely would

the guy I was going out with said 'i love you' a few times to me. and he did it in a really sweet way, but I told him that I didn't believe him because I was treated badly in the past. and he even said it after that a few times, and said, I know you don't believe me but I mean it.
when he first said it to me we were only together for like 2 months.
i realllly have a lot of feelings for him now, but he has to end it with me because he doesnt want a relationship.

yepppp. A couple of guys have done that to me after knowing one of them for like 2 weeks and the other one a couple months. The one that I knew for 2 weeks said it because he thought that I would let him get in my pants and the other said it for almost the same reason. Guys think that by saying I love you it will make us fall in love with them or something and let them have their way with us. Don't listen to a guy when they say they love you unless you have known them for more than 8 months.

Yes. A man who lies about it does it to get his way and to get sex. Make his actions speak louder than his words. If he says I love you but beats on you, disregards you, is mentally abusive or cheats he is just saying it. Love is shown by actions, not the words alone.

I believe some guys would say that and maybe some girls, too..sometimes just to make you feel better about yourself--or he maybe thinks he knows what love is- sometimes he wants to be at the point where he could really mean it...
