For a crush:
There’s a lot of uncertainty for the two of you, so not knowing if he loves you or not is very stressful. Since he is your crush I imagine you’ve been paying a lot of attention to him. Does he make an effort to talk to you, ask you about your days and hobbies? Does he ask if you’ll be at that party this weekend or try to find ways to be around you? If the answer so far has been mostly No then maybe he’s not good at expressing his thoughts verbally and you need to see his actions instead. Does he find ways to be near you? Does he do little things that make your life easier?
If the answer is still No then a lack of maturity could be the issue or sadly, he just might not be that into you (link older article). One last thing to keep in mind though is have you made it obvious to him that you like him? Could he read those questions and mostly answer Yes? Have you been honest and straightforward “I like you, I would like to date you, what do you think?”
I know it’s scary to put yourself out there like that but this not knowing will fill you with doubt and destroy your peace of mind from the inside out so even if it’s not the answer you’re hoping for, it’s better to know for sure than always wonder.
For a relationship:
It’s very possible you might have a different love language than your significant other. That’s very common and nothing to fear. The way in which you show love and expect it to be shown back to you might be very different than the way your significant other naturally shows their love for you. For example, you might be vocal about your love, writing love letters, showering them with compliments, and always ending an exchange with ‘I love you’. Your significant other might be quiet or reserved and you may be hurt that they never compliment you or say I Love You first. This is where it’s important to 1. Figure out your love language and your SO’s love language and 2. Directly communicate to your SO that you need to be shown some love in your love language (to continue the example, you might ask them to write you a note of appreciate or love or to make the effort to compliment you more).
It’s important you find out the love language of your SO other because this can help you notice the ways in which they ARE showing their love. For example, they might show love by spending quality time together. No matter how busy their schedule is, they make sure that they are home to spend every dinner with you. And sure, you are capable of walking the dog by yourself, but they walk with you every time for that extra one on one time. This extra effort may have been going by unnoticed to you. You may have even gotten annoyed when they asked you to check your social media apps after dinner but now you’re realized how much they cherish that time of undivided attention and connection.
Aside from realizing all the ways you are being shown love, you can also make the effort to show them love in that same way as well. You’ll feel connected again when you start making this effort along with seeing them make the effort to speak your love language too.
