An appropriate mixture of pathos, logos, and ethos makes for a strong introduction to the perennial (universally occurring and recurring) interpersonal resonance known as love.

I made some revisions here and there, for example,

I shifted the redundancy in this transition "love is not always easy. It is also very difficult"

to a sharper incline towards "love hurts" to set up the narrative dimension of your argument. It seems like personal testimony, and I think the force of this testimony, if unbridled and made into 1st person narrative, would render more effective definitional forms. The opening series of questions sets this up--so, amp it up, I say.

Also found some simple spelling errors, so remember to leave time for those single-minded edit-passes as you work.
