How would you interpret this card in terms of one person's feelings towards another?
I associate it with a love triangle, heartache, pain, drama, hurting someone, or being hurt. So, does this card suggest that the person feels you might hurt them, or that they anticipate hurting you? This happens to be one of my least favorite cards, and lately, it keeps appearing daily.
At times, this card emerges when there's a need to communicate something, often something painful, because leaving it unspoken feels like it's eating away at one's soul.

The 3 of Swords can suggest a sense of feeling 'cut' or slighted in some manner. On occasion, it comes up for me to predict a literal paper cut or a minor injury of some sort. 
I have often interpreted the 3 of Swords as representing a lack of communication, which can either result from or lead to heartache. Another possible meaning is heartbreak, particularly when a third person ("the other woman/man") is involved. It can convey feelings of being left out, self-pity, jealousy, or envy.
Allow me to share two personal examples that might provide further insight:
On a particular morning, I drew the 3 of Swords as my card for the day, alongside the 9 of Swords and 10 of Swords. I was grappling with issues in my best friendship, feeling jealous of the time my friend spent with his new girlfriend. I experienced a sense of being left out and lonely but couldn't communicate my feelings, knowing they were unreasonable. This lack of communication led to an argument, and I later discovered he had kept important health concerns from me, leaving me feeling betrayed. Although we eventually resolved our differences, it was a true 3 of Swords moment for me: jealousy, isolation, heartache, and betrayal.
Following my breakup, I consistently drew the 3 of Swords. I was in denial about my grief, and the card encouraged me to acknowledge my broken heart as a necessary step toward healing.
I hope these examples provide some clarity!
