Do you know that expression "love is blind"? Love is blind because when our emotions are so involved, our brain doesn't always operate at maximum efficiency! Everyone has experienced that "head over heels" feeling, and it's exhilarating! It's like walking through air, being happy and feeling the exuberance of youth, all at the same time.

You'll often notice that you have a silly smile on your face for no particular reason, and you are so caught up in your feelings for the other person that you would be oblivious if the world stopped spinning. However, how confident are you that the person is really free?

What phone number do they want you to use? Will they only volunteer their cell phone number? Have you been invited back to their place? Do they sometimes need to leave urgently when the two of you are doing something?

Pull your head out of the clouds and honestly ask yourself if it seems like they have something to hide. The answer might not be pretty, so the question can be tough to ask. Of course you don't want to imagine the love of your life lying to you or being married to someone else. But this is a grim reality for many people.

If you are unsure, there are a few things you can do to tell whether or not it is alright to continue on or if you need to have caution. Pay attention to the person. Do they act like they have other things to do? Are they always checking the time or do they always have to leave suddenly? If so, they may have lied to their families and have given themselves so much time to spend with you before they have to return to their 'other lives.'

Have you been introduced to his or her family? There is a good chance that they are really single if they want to introduce you to their parents, siblings, or other family members. You should proceed with caution, however, if some time has passed and they are still not showing any signs that they want you to meet their family.

Another investigative step to take is doing a reverse phone number search online. Just enter their number and it will give you their address, or vice versa. You could learn information about them you didn't know before, and you can also find out other tidbits about them.

You can find out if someone is married, has been married or divorced. you can also do a background check to see if someone has ever been charged with any crimes. These can be done to ease your mind.

If they are not married, perhaps it is just a fear of commitment or something else keeping them from having you over to meet their family. Either way, at least you will know that you're not contributing to the pain of someone else. If you are in doubt, follow the advice and tips above so that you won't have to worry and wonder any longer.
