how to know if u truly like them

i usually lose the intense longing for someone once my feelings get reciprocated.

i am stuck in a dilemma of whether or not i should stop talking to someone because i feel rather bored with them.

although, the thing that's bugging me is why do i have a hard time letting go of this connection if i am truly not interested in them?

help. how do u know if u like them or not, is it my attachment issue that's ruining this for me?

thx.
