OP, so u wana destroy anoda woman's marriage,
Weren't u aware he was married b4 falling stupidly in love with him,
Is he having major issues with his wife,
What makes u think if he does marry u as a 2nd wife, he won't av gurlfrnd asides u & d 1st wife..
You don't even know, if he's a womaniser cos he may probably av oda concubines like u daz he's claiming to also love.. Truth is,
I am not judging u cos at times, we may not be able to control who we fall in love with but, u shud be able to make proper research bkus at d end, u cud b at d losing end..remember, u are in your 30's already..except of course, he's an alhaji or a king who could av as many wives as dey so desire...
Bottom line, USE YOUR HEAD
