If you mean it? as many times as you feel it is needed in a situation, you argue with her, you end it by telling her you love her, you see her and she appears down, tell her you love her, you see her and she's looking amazing tell her so and tell her you love her. Starting to see the pattern here?

If you don't actually love her then NEVER say those words. Those 3 little words mean a lot to women "I love you" is just something that makes any break up with a girl so much harder and more hurtful. If you don't love her and she tells you she loves you then do what I used to do in that situation...

Girl "I love you baby, you make me so happy" (yada yada yada)
Me "Yeah...*Kisses her* you're so cute baby" (avoidance but the kiss and the change of topic if performed properly means she forgets I never actually said I loved her too.

Another way of avoiding it is to simply use the responses "that's nice", "me too" (this one is tricky, many will see it as you are telling her you love her, I see it for what it is. Put in context of she told you she loves you replying "me too" essentially says that you love yourself also...god I love the english language), "Do you?" Pretty much anything goes as long as you never say those 3 little words. Believe me I got a lot of practice in avoiding those 3 little words and it makes all the difference in the break up because when they tell you "but you said you loved me!" *cue crying* you can say "well actually name a time I said the 3 words "I love you"? Because I think you'll find I never said those at all ever.

Thankfully now I don't have to avoid those 3 little words as I do really love Tinker's
