Sacrificial Behavior
As you become more in love with your person, you likely become willing to make sacrifices and compromise for the betterment of them and the relationship. This is thought to be a result of the vagus nerve and how it is affected by love. You and your partner become synced through the vagus nerve, according to science — this sync makes you feel more in rhythm and connected to your partner, which can lead to a feeling of willingness to sacrifice and oneness.
Recurring Thought Patterns
We’ve all experienced the phenomenon of constantly thinking about our person. This is partly due to the dopamine reward we get from thinking of them, but also due to the anterior cingulate cortex. This part of the brain is linked to obsessive compulsive behavior, which may explain why it could be activated when you are obsessively thinking about your partner.
Jealous Feelings
Jealousy is typically inevitable in relationships. It is a natural feeling that occurs when you love someone, and is actually scientifically normal. When it is not excessive and possessive, jealousy can actually promote deeper bond and connection within the relationship.
