Have you ever experienced loving someone who you shouldn't? Not because they were the rebel child, the bad boy or were covered in tattoos that your mom hated- but because you know you will never be with them.

1. They are in a relationship

Okay, this one is clear. We all have crushes on people, and occasionally the person might be in a relationship. However, sometimes this "crush" is much more than that. Sometimes it is an overwhelming feeling, when your heart skips a beat and seeing them with their boyfriend or girlfriend utterly tears you apart. This is when you should realize that it is time to step away from this relationship. You never want to be the guy/girl who gets in between a relationship.

2. They are your best friend.

Everyone says, "marry your best friend", but how true is this? Sometimes our best friend is the last person we should be in love with. Imagine losing that person-- it's a terrible feeling. Now imagine loving that person and being in a relationship...and then losing them. Sometimes it's best to not try out a relationship when it could possibly tear apart your friendship for good.

3. They say all of the right things.

The midnight texts. The random phone calls. The laughing until 3am about the silliest things. These are all great aspects of any relationship, but sometimes they are too good to be true. Things change when relationships become more than just friendship. People change and some of these best moments may never be the same again. Great memories could still be had, but the friendship will always be different.

4. When you tell your parents that you are talking to someone and their reaction is, "Please don't let it be _____."

Ok, I am sure that we have all experienced our parents’ disapproval in some way, but have you ever experienced this? Your parents know how much you love this friend, but they also know how badly you might get hurt. Maybe he or she doesn't have a good track record with your parents or seems to jump from relationship to relationship. Either way, your parents know that you can do better. Most likely, your parents are trying to protect you from loving someone who isn't right for you.

5. You love them more than they will ever understand.

Loving someone is hard. Loving your best friend more than a friend is even harder. If you struggle to differentiate between friend love and romantic love, you probably shouldn't be with this person. Sometimes we love people because we so desperately want to be with them. However, we tend to ignore the fact that this person can never truly understand the extent of love that we have for them.
