But I also think that people should be allowed to vent frustrations on here without always being expected to leave their marriage.
People throw out LTB a lot where the DH is the problem and continues to be the problem.
I also think a single event that causes frustration, is very different to this situation where the best resolution would be the child not coming over.
If someone complained about not liking their biological child and wishing they weren't there or always preferring it when they were out of the house, leaving the child isn't an option even if you end the relationship...unless you want to hand them over to social services or abandon them.
The difference with a SC is you don't have parental responsibility and you can walk away, unlike a biological parent.
It's not always clear whether someone is posting for advice, to vent or validation of their feelings.
Feelings are so individual, but human beings so often want to know they're not alone with those feelings...as it normalises them. They don't feel so bad about it.
A million other people in your situation may not feel like you....and that's okay. It's how you feel and how it affects you that's important.
They're not in your relationship and if this aspect of your relationship is a source of anxiety/stress/dread or similar...it's not a bad thing to walk away from it for your own mental health and well-being.
The alternative is to label it as a vent...say something like ^I don't like it when the SC come over, but it's not such a hardship that I'm going to end the relationship. The good outweighs the bad and I'll just put up with it for the next however many more years.
In the meanwhile you may have kids yourself, which often intensifies the negative feelings and you see yourself as a nice little family unit most of the time (minus stepchild) and you just wish SC didn't come over at all. The feelings of dread and heart sinking have been used by many on the situation.
