try this out http://www.mangago.me/read-manga/cherry_ichijou_lemon/ (he was already divorced but it was quite because of the uke)
http://www.mangago.me/read-manga/kyuuso_ha_cheese_no_yume_omiru/ (and the sequel http://www.mangago.me/read-manga/sojou_no_koi_wa_nido_haneru/ ) Highly recommended if you haven't read it!
Darling 3rd couple, Kawaii Hito
