No: How someone feels determines the meaning of their words.
Just because the "listener" is tired of hearing it or feels forced to say it back when (they) don't want to does not mean the original person stating it feelings have changed.
Having said that the words "I love you" mean different things to different people. Generally speaking a person will say to themselves: "If he/she really loved me then they would....etc"
One great question to ask a person early on is: "How do you know when you are loved?"
Based upon their answer you can tell if you're the (right) person for them. We all have our expectations of what love is supposed to look like. If we're not getting it we say they don't love us!
Lastly if (you) are "in love" it's hard to imagine you getting tired of hearing your significant other tell you that (they) love you!
Very often the person who wants their mate to change does so because (they) themselves want to change or stop doing something.
If you really believe someone is (lying) to you when they say "I love you" then you should dump them! You can't trust a liar.
