My parents have mostly been happy, I think. They say they have, but acknowledge that they often have very big arguments, which used to make me wish that either they'd just split up, or stop arguing. Obviously real life isn't that simple, but that was my childish perspective.
My dad is like me, only I'm a little less rough around the edges: he likes to have a rant when he's wound up, then after he's said his piece, he's okay again. Me & my dad can go toe to toe, but be hugging 5 minutes later with no hard feelings.
My mum is the opposite, & in fact more like my sister (although my sister doesn't enjoy that comparison
), in that she seethes so as to not rock the boat, & begins to harbour resentment. Often, my dad shouting will upset her & she'll be upset & distant with him for several days. This in turn enrages my dad, as he thinks that it should all be over by a certain point.
I also have had some rather uncomfortable discussions with each of them about their sex life - my dad works in a very testosterone-fuelled environment (actually hugely prone to infidelity - WWIFN would see it as a huge lifestyle vulnerability, but I truly believe that my dad has never strayed, for a number of reasons) & would happily have sex several times a day. My mum has a low sex drive anyway, I think, & combined with any annoyance with my dad, means that there's a large discrepancy. That's the main bone of contention within the marriage. (Hours of fun, those conversations
)
In some ways, I think that they were stupid to marry. They were very young & had not lived together beforehand (mostly because my dad worked away), so things like the sex drive incompatibility never came to light until it was too late. They were also the first 'proper' relationship for each other (sex included) & I wonder if perhaps they settled. But then I can't imagine that they'd be happier apart, although there are aspects of their lives which would be better if they separated, I think. Despite all of that, they are still very much in love.
It affected me most by making me believe that getting married & having a family young was a risk with good odds. That did not pay off for me. I also, as I say, often wished that they'd just decide what they were going to do & stick to it. I usually thought that they'd split. & I have since had several conversations with each of them about how they're getting older & the idea of time passing is a motivating factor in wanting to leave with every big argument. I still don't know 100% if they'll last the course. My sister will move out this summer, so we'll see, I suppose.
I've not yet read your original thread & I'm not sure if my parents' relationship has any bearing on your own. I suppose my point is that it's not clear cut. & even if things are generally okay, it can still be fairly traumatic for the children. & judging by AF's responses on this thread & the fact that you're posting, your marriage is probably a lot worse than my parents'.
