Still... Why is his name Mochiduki? There's no "du" sound in Japanese, that's only for foreign language sounds...
It's bothering me so bad Σ(  ̄□ ̄||)

It's bothering me too ahah It should be Mochizuki (that's how it's pronounced)... I guess it's because some people (and also dictionaries etc) write づ as 'du', but that's not correct; its pronunciation is still 'zu'
The "I found him first" is such a childish way for choosing a lover. Just because you found him first, it doesn't mean he's yours. He's not a thing (╯°Д °)╯╧╧
Secondly, if you really had cared about him that much, you shouldn't have treated him so badly and hurt him so many times. You can be as sense as you want, but giving priority to another person, your fiance, over your lover is definitely being an asshole.
Also, this way you hurt both your lover and your fiance. You're being an asshole to two people, not one person ┑( ̄Д  ̄)┍
