What makes a relationship unrealistic to pursue?

when no one is really happy

when you're the one who's so in love and the other person doesn't even care if you're still alive or not.

when that relationship will only hurt everyone involve (which including family and friends of the lovers).

I think that is the relationship he or she fell in love someone not me

when they are gay. I really like her but she's lesbian
I'm SOL

Nothing is literally unrealistic if both parties truly desire it and will commit to each other. If both aren't 100% about the relationship it won't work.




So my answer is: absolutely nothing.

If it not worth to pursue

When the other person in the relationship hates you.

when there isnt a 2-way connection
