Ah, unrequited love. When your heart is all "pitter patter" and your stomach is a playground for butterflies. Your mind is beyond consumed with your crush and all you can hope and pray is that he or she wants you just as badly.

We can all dream for a match made in heaven, but sometimes the balance is off. Just because you're gaga for that perfect person, in their eyes, you're simply not their "the one."

Here are 4 signs to look out for to learn if your crush is just not that into you. Save yourself from heartache and close that door before it hits you on the ass. Your soul mate is out there, but you'll never meet if you don't get over the crush that's not crushing on you.

1. It's Always About Them

Does the one you adore have plenty to talk about with you… as long as it's all about them? You may think that any conversation is a positive sign, but if the guy or gal has no interest in your day, hopes, or dreams, they're probably just enjoying the attention you're giving them.

As per A New Mode, "If a guy (or gal) shows no interest or excitement over finding out who you are, it's not a good sign." Beliefnet adds, "When (someone) is into you, they value what's going on in your life, even the little things."

Another sign of disinterest is when the relationship is only at their convenience. As Vixen Daily notes, "You only hang out when it works for them. If he (or she) cares about you, he's (or she's) going to put in an effort to spend time with you. That means that they'll come over to your place, even though it'd be easier for you to come over to theirs."

2. You Make the First Move… Always

Is it you who is the one to say hello, call first, or ask your crush out for coffee? Sure, they may agree to a date, but someone who's really interested will take the initiative some of the time.

Elite Dailynotes, "If you always send the first text message, you may come across as needy, but in all actuality, it's not the case. Shouldn't it be at least 50/50? Vixen Daily adds, "(If someone likes you) they're going to make an effort to see you."

People like attention geared towards them, so your efforts received as flattering. But you deserve to be flattered back with some doting placed upon you. If you find yourself waiting around for calls, texts, or offers for drinks, take a deep breath and realize this guy or gal isn't all too interested in pursuing a relationship.

3. They Never Get Back to You

If he or she is into you, they're calling (or texting) back ASAP. Games are for kids and impoliteness is for no one. Wasting time awaiting a response from someone who seems to have far too many better things to do is no way to spend your dating years.

According to A New Mode, "If he's into you, it doesn't matter how busy he is, he'll take 30 of the 86,400 seconds in a day to reach out to you, even if it's just to send a quick text. A guy pulling out the excuses early on is always a bad omen."

You should be able to rely on someone to give you the time of day, at the very least, to determine if there's interest. As Beliefnet puts it, "A person interested in you wants to build the relationship and communication is a major part of that. While a little distance at the start of a relationship isn't uncommon, a lackluster effort with odd excuses as to why is a major sign that he's not that into you."

4. You Never Met Their Friends or Family

If you've been seeing someone for a while but you're not convinced they're head over heels, meeting (or not meeting) their friends and family is a telltale sign. You may just be a "for the moment" romance or a basic "booty call" if you're never introduced to anyone in this person's life.

According to Vixen Daily, "If he's (or she's) actually into you, you're going to meet his (or her) friends because he (or she) wants their opinions. He (or she) cares what his (or her) friends think." Beliefnet adds, "If he (or she) doesn't want to bring you around the people that matter most, he's (or she's) not interested in progressing with you."

On a similar note, if your crush has no interest in meeting people close to you, it's a red flag that the relationship isn't where you want it to be. Metro notes, "That introduction doesn't seem necessary for him (or her). Because. Well. He's (or she's) just not that down. Also, he (or she) is fully aware you'll look upon it as a 'step in the right direction' which freaks him (or her) out.
