Blogs are generally a place where those who they belong to can come and write about their feelings, thoughts and what events happen in their lives. I am having a bit of a reaction to M writing on your blog ak, denying that your experience of your reality is valid. There is no right or wrong in this. Just different experiences of events and what is going on for you both.
When someone tells another that their version of their reality is not valid it creates doubt for them. Parents tend to do this with children and the doubt that is created, that their experience and gut feels aren't valid, turns them into doubtful adults who follow what others tell them because they believe that other peoples reality is more valuable than their own.
Ak, this is your blog, and you can do with it what you will. If you are okay with M reflecting her feelings and thoughts about what you feel and think on here then that's fine, but I would suggest that the usefulness in blogging will be gone as a result and I would think that eventually you will not bother as you may feel that your privacy is threatened.
You seem to have a lot of doubt already that this is a good relationship dynamic for you ak. Your struggle is evident. That is very valid and I would hope no one is trying to convince you that you should just deal with it and suck it up. Walking through your emotions and getting to the route of what is going on for you will mean that you can discover what needs aren't being met for you. Once you have made a list of those, then you can start being creative about how to get them met and invite the others to help you with that. It would be important to voice what you need, however ludicrous and over the top it might sound. That would be the beginning of negotiating. I hope you continue to blog here to sort stuff out.
M, I totally get that you have a point of view and I am not suggesting that that should not be respected. Perhaps starting your own blog or talking in private with ak would be a better idea than questioning ak's thoughts here. Maybe this should be her space and her place of safety to explore and get feed back from others on HER version of what goes on. I'm assuming that you didn't talk about it with ak before writing here M and perhaps asking permission to respond would be more respectful?
Just a thought from someone witnessing.
