Love is blind

I must agree that love is blind.

When one is in love, he/she will only have her/him in the eyes. One will accompany him/her to go the things that they like. Can't see the bad pts only the good pts

But I just want to ask, after getting into the relationship, why one will ask why? why can't do this, why can't do that? Can I say that we are not longer in love anymore?

I want to be in love but I am too tired to try.
I want to try to love but no confidence...
