Is detachment - giving up on your manifestation?

Detachment is being explained in various ways across the community, but it can seem contradictory. I think this is grounds for fruitful discussion.

The Law of Attraction itself states that like attracts like, which is why in theory the most dominant thoughts should manifest outward no matter what.

However, people will say that the manifestation will only arrive when you detach, which is interesting. Let's say detachment is being indifferent to whether you have your desire or not, but then how can you possibly manifest it if it's not even on your mind anymore?

If you don't think about it - the universe assumes you don't care about it, right?

For example, I have failed to manifest a soulmate relationship for over a year, yet I have manifested other things in my life before. The law does not seem to be working universally on everything, and that's when people bring up detachment - which I never really understood.

Personally, I'm gradually moving away from the community and its philosophy because it's becoming frustrating due to the mental gymnastics and straight up contradictions people are proposing.

How do you understand the Law of Attraction vs. the Law of Detachment?
