This I can understand and I feel for you. I can believe that step-moms deserve a safe space and that venting is good....and I do...but as a biomom (and it's weird for me to even have to use that word) I live in abject terror of these feelings. I know that some of the single moms have a small private board that only single moms from MDC are allowed on to and I wonder if something similar for step-moms might help. Not that I don't think this is the place for stating honest feelings but it's hard to read this and not post.
When I find it hard to read threads or forums here, I make the choice to just stay out them. Or if a particular poster is causing me angst, not because of UA violations, but just making me uncomfortable, I've found that using the ignore button keeps my sanity intact. Not saying you need to do that, but if our posts and feelings are striking terror in you, it might be time to step back. (And if you could hear me, I'm saying this gently and with complete understanding.)
We are all struggling through things. My issues with my family situation aren't going to be resolved through something you do, anymore than your particular situation will be changed by what I do, or what I feel. None of us have done anything to hurt any other of us here, but i think we still seem to take things personally. Human nature, I guess.
I thought about pm'ing the person who started the single mom offshoot to see how they did it. It does seem like a nice idea. Thanks.
