Okay, so I'm not married but I've had enough family-oriented problems to have been married to like..50 guys.
One of the main problems we had was that we were young, way too young. I understand that, and even at the time I understood that, but that didn't mean that them being kind of cold towards me didn't hurt.
I used to be terrified to even go over Ben's house, and when I was there I was so meek and timid I probably came close to giving myself a heart attack or a fit or something. I can still be apprehensive, scared to say the wrong thing or do something and suddenly find that they hate me again. Not that they ever hated me (or so Ben says) but it certainly felt that way.
It took me years to be able to call them both by their first names. For a long while after I was calling his mom by her first name I was stuck in between Brother King and Tom with his dad. It's was like the "hey yoooouu" phaze or something. And it was really hard because Ben hit it off so well with my parents because they're sooo super easy going. Ben and my dad have long talks about everything like trains or whatever and I couldn't even say hi to his parents for a while without wanting to hide under a chair or something.
(I'm writing a novel here too) Our families aren't too different. I'm pretty close to both my parents, and I'm still a little girl with my mommy (like, I can sit on her lap still) and Ben's not like that with his parents really (that'd be kinda weird..the whole lap thing). They're more independent, and while they're still all close they're not as affectionate which is fine, because I have trouble being that close to people outside my family who aren't my super-best friends.
I'm not even done reading but, you're just classy...I mean it.
It takes guts to admit some of the stuff you mentioned in the outset :)
