When looking at social media and relationships, there are plenty of people who get upset that their significant other doesn't post about them often enough. There are also those who feel social media is a downfall to their relationship, as it causes distrust between the couple.
I'm no love doctor, but this lack of distrust is unhealthy. Social media should be fun. It should be a way to interact with friends and express hobbies to the world. It also can be a way to advertise your "hot new bae," but if you end up really are angry that your significant other isn't posting about as much about you as you are with them, you may need a reality check.
Yes cute, lovey posts can be fun, but social media does not define a relationship. Respect, trust, and love are what define a healthy relationship. You do not have to have the words "single" or "taken" in your bio. Those words do not define or describe you.
Social media seems like it can be a trap for relationships. If your significant other likes a picture of an ex, or of a person who you may not enjoy to be in the presence of, there is no need to psycho analyze what these "likes" mean. In the long run, they mean nothing because if a silly "like" button is the determining factor in how you trust your partner, there are probably deep rooted problems that have yet to arise.
Compulsively checking your partner's social media is not going to make your relationship better or worse, if you don't trust this person, you need to talk it out, not overthink about the situation by stalking their Instagram.
Relationships take time and work, and lots of trust. Technology is all around us, so let your partner behave on social media how they want to. If they are worthy of being in a relationship with you, they won't set out to "like" anyone else.
