Short answer: Of course

Long answer:In my opinion:

I don't think love is always at first sight, if that's what you mean. In fact, that kind of love is probably pretty rare (and more than likely lust). True love takes time. You can feel strong love for someone you have just met. You can feel that attraction and spark where you just seem to click so perfectly, but it takes time to really know a person well. So ... you can fall quickly for someone, and they can fall quickly for you, but there's a chance they are wrong for you. I THINK you probably can know if it is right after getting to know each other well and going through things together.

Ya know.. now that I am actually writing this down, I realize how little I know. I'm 33 and a single mother of four kids. There was a time I thought their dad was the one for me...then I got to know him better. lol. Plus I was quite young when we started dating. I think sometimes we just want love so much that it feels more important that there is someone to love, no matter who it is, than the right one for you, and that's when you start to see someone as being your soulmate because it's what you want to see, and you ignore their faults because you are blind to the possibility of them not being your soulmate. (I've used the term love loosely here btw)

To answer your question, it is entirely possible (I believe) for someone to overlook someone wonderful right in front of them, because they are so focused on being infatuated with someone, or a particular idea of someone.

Whether you believe in the bible or not, there is an excellent passage on love that I always turn to when I am questioning if something is real love or not...something I should have read often in the past, but was too caught up in something wrong to have time to think.

1 Corinthians 13Love

¹If I speak in the tongues^[a] of men and of angels, but have not love, I am only a resounding gong or a clanging cymbal. ²If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing. ³If I give all I possess to the poor and surrender my body to the flames,^[b] but have not love, I gain nothing.

⁴Love is patient, love is kind. It does not envy, it does not boast, it is not proud. ⁵It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. ⁶Love does not delight in evil but rejoices with the truth. ⁷It always protects, always trusts, always hopes, always perseveres.

⁸Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away. ⁹For we know in part and we prophesy in part, ¹⁰but when perfection comes, the imperfect disappears. ¹¹When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put childish ways behind me. ¹²Now we see but a poor reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known.

¹³And now these three remain: faith, hope and love. But the greatest of these is love.

I know this was really long... I hope it helped in some way.
