There's an awful lot of what I'd call "unhelpful" comments in this thread. Everyone's allowed to express their opinion of course, but the dozens of posts along the lines of "Durrr, youre'are an idiots OP, this is yur fault and you deserveded it, just be a hero like me and say NO - y u even nedd hadvice on this grow a spine ???1!?/1!?1!?/! ?" really aren't working for me. Not at all. Not even a little bit.
Those kind of responses might inadvertently make a casual observer think the people who wrote them don't understand what the real issue is, and perhaps they're entirely devoid of self awareness and their entire personality is being unpleasant - "I say as I see and speak as I find, and people respect me for it!!" [Spoiler Alert: they don't.]
The actual issue is that OP is "conflict averse", and there is nothing at all wrong with that. Most people are. I'd say she's got some things going on with self image/value/confidence/worth and the like as well, which again is perfectly fine and normal. So what happens when you tell someone just like OP to "grow a spine?", or that they're "stupid", or "this is all your own fault"? What are the thought processes behind it?
Do they think they're helping in any way shape or form? Because they're not, they're making things worse.
Do they think they're offering useful, practical advice? If they said to me "Stevie, can you reach that thing down for me please, it's too high up for me?" and I replied with "psh, why don't you just grow really tall like me and get it yourself you idiot?" would they be happy with it?
Do they think they're somehow empowering the OP-like person? None of us know each others story, none of us know how each other got to the point we're at now. None of us know what kinds of things people have been through that shaped us. Just because someone similar to OP asks for our advice on something but doesn't start their thread with "childhood trauma.. sa.. foster care.. abuse.. care homes.. violence.. borstal.. sa.. oh, and does anyone know how to unblock the kitchen sink please?" DOES NOT mean they're playing life with the same hand of cards that YOU were dealt.
An observer could be forgiven for thinking that the kind of people who write these kinds of comments are the exact same people who behave in the manner that the woman taking advantage of OP does. The exact same people who at school parroted "but Ma'am it's not fair!! He could have just said no but he didn't! So how was I to know he didn't want me to throw his birthday cake on the floor and stamp on it! Why am I in trouble? This is all his fault for not saying no!!".
And thus ends today's instalment of The Gospel According to Frogpole.
That is all.
