(historical bg fun reasoning)
Henry Jr - famously married young even by the standards of the day (at 5 yrs old) but by all accounts seems to have been loving and faithful
Geoffrey - described by Bertran de Born as "Count Geoffrey, who doesn't know how to please the ladies," and appears in one of Gace Brulé's poems as being bewildered at people who act crazy for love. However, he had the most successful relationship in the end so there's that
Philippe - not much here just for someone very demanding and difficult to deal with the common denominator in his failrelationships is....himself....
Richard - We have much less info to go on regarding his interpersonal relationships--had that privacy on lockdown! Which leaves a lot of room for nosy speculators of course.
