@Vanessa About marriage and parent's approval,what do you think can be a reason for not approving it?Only if there is a danger(like someone using drugs,being violent,etc...)or too based on their social class(so no rich people with poor ones,or such)?Do you think parents may have some impact on deciding who their sons/daughters will marry(a bit like arranged marriage)or just approve or disapprove their choice?

@Laura Social class is mostly the case for parents' approval. Not only money, but occupation, education, etc. The French word "mesalliance" (for some reason misterpoll doesn't allow accents, but you know what I mean) describes it the best. Both arranged marriage or just approval should work. Maybe I'm wrong, but it seems your parents are not happy with your non-straight relationship.
Safety is another side. I doubt your or Catherine's parents would approve marriage to one of those refugees. Looking further I think more young girls in Europe should wear chastity belts because of this.

@Vanessa Yes,I think "mesalliance" can be the right word,even if not used often in french,nowadays.My parents never took much care about social class or money,but they won't allow me to date someone who look as a "bad boy" or neglected,nor if they think it can be dangerous(someone using/dealing drugs,someone who seems violent...).Poor education may lead to not getting the approval,too.Occupation...Hum,not sure which ones would be disapproved.
Arranged marriage(even if not exactly the same than forced marriage,but not accepting it can be difficult)would be awful for me,having to marry(and I guess divorce is not accepted in such cases)someone I don't love would be very hard,and I'm not sure I would accept it,even if it means not seeing my family anymore.However,I think it can be influenced by education...My family never suggested it,but,maybe,if it is more traditionnal in the family(even more if parents marriage was an arranged one),it can be accepted more easily.Even if not common at all nowadays;I don't think many families still do it,and even less people accept to obey it.
Safety is important for my parents too,as I said,they won't approve somone who can beat me or make me using drugs/be drunk.etc...They take care of it a lot.Not sure if they allow or not dating a refugee,it'll depend on each case.If he is not neglected,educated,want to continue studying or working,not using drugs/alcohol,is caring for me,they may accept it.

@Laura It seems you understand the word "mesalliance" right. Although it's not used widely, but well educated people know what it means, unless their brains are poisoned by this "tolerance", etc. I don't know you parents' positions about it (why know just ask using this word?), but you haven't talked to them about marriage seriously yet. Same about your relationship with Emile. As long as you wear a belt, you can date whoever you wish, but marriage is different.
I'm not talking about a refugee who is "not neglected,educated,want to continue studying or working,not using drugs/alcohol", but what you have in reality and that's far away from your description. Probably there are few exception, but I would prefer to stay away from them. There are occupations, you also should start away from, but I don't want to list it out here, because that's off-topic.

@Vanessa Sure,my parents took care to know who I date,and I know more or less what they won't accept,so I know it is totally useless to try dating someone who use drugs,or,is impolite,or look bad,even if he's nice with me(some example,there is a lot of other examples),so I generally don't start to date them,knowing they won't be accepted and my parents will make me break-up with them.So,in a way,even if it is way more free than an arranged marriage,they can limit the choice of people I could start a relationship with and marry.
