We're all guilty of it. We think we have this incredible Great Wall of China protecting our vulnerability; however, we tend to overestimate its security with defense mechanisms that could potentially hurt us in the long-term, concerning the formation of future relationships.
We must let others in to embrace the process of falling for someone
If you're like me, constantly busy and preoccupied with life's demands (sometimes going days without proper inhalation and exhalation), we become almost numb and ignorant of our emotions, mostly as a result from not putting ourselves out there. But this lack of experience is wrongly mistaken for the notion of attachment resistance. It's OK to focus on yourself, but after a while, it is necessary and fun to reawaken those feelings and jubilant moods associated with falling for someone, because in the midst of life's madness, we often forget how to feel.
Do not attempt to avoid to "catch feels" like it's the plague
We're consistently bombarded with false advice from society to avoid "catching feels," or falling for someone, no matter the costs. Why is it suddenly so frowned upon to actually like someone you met? Why should we feel shame in wanting to continue a relationship with this person? Dating is evidently complicated in the 21st century, but don't let this make you try to consciously repress those newly-formed feelings since repression essentially leads to escalation. Embrace the feels because it's the human thing to do.
Loosen your wall's bricks with vulnerability
Some of our jerk-alert senses are more activated than others, mostly due to past experiences, but it's important to hammer into our heads that they're not all the same.
Stop lying to yourself. No matter how much you repress it, you will feel, you will get attached, and you will allow yourself to do this, despite what the norm is for what "dating" is today. Break off from your defense mechanisms and your wall will slowly follow. Remember: "catching feels" is not synonymous with sickness, but with embracing the human capacity to feel that we all too often neglect.
