<human>: Can you give me a shortened version of the text?

My boyfriend [24m] of three years/fiance of six months and I [[20x]] were postponing announcing our engagement since one of his cousins was getting married and we didn't want to steal her thunder.  Alas, though, the time has arrived to suck it up and tell his family (I'm from a bad family situation and thus not really on good terms with my parents, so we won't be officially informing that side). 

So far we've only let slip to one of my close friends, and to his brother. We thought we'd start by telling his parents in person since they live near by (we're both on a college campus about two hours from their house), but I for one am a little nervous about their reactions since we're young and still in school (don't have a date set for a wedding though, and not aiming for one for at least another two years), and also just coming from such a clan of volatile people, I'm in general not used to tactful behavior, and my mind keeps jumping to the worst possible reactions. 

The Boyfriend assures me that his parents will be delighted by the news, and I definitely believe him on a logical level, but the illogical part of me is freaking out, and I feel like I need some more 3rd party reassurance. My questions, essentially, are:

**1)** Any tips for what to say and in what setting? I'm horrible with wording things nicely, and even worse if there's a group of people present. 

**2)** Is there any legitimate reason I should be concerned about his parents reacting badly? I get along great with his family, and he and I have never yet had any particular relationship problems. (And no, they don't care if I'm a girl or a boy, and yes, our state would let us get legally married.)

**3)** Do you have any encouraging or amusing success stories of your own surrounding engagements/weddings that might sooth a poor paranoid suitor's nerves?
<bot>: Excessively nervous about getting a bad reaction from fiance's parents over our engagement since my own family is a bunch of douchebags.
