FA relationship pattern HELP: Do I leave??

Do you know how to selfregulate ?

This is the watertank exercise jebkinnisonforum.com/post/31863 which is recommeneded to help you to land your nervesystem 
There are also different techniques you van use if you go into freeze - the woo sound ect.

To me it sounds like you have been passive with an passive angerpattern and now you just had enough so you are about to switch to the aggressive angerpattern. Exploding is NOT going to help you and the anger explosion can overwhelm your nervesystem and you can risk going into a collapse state afterwards.
Also theres a chance that he is not able to listen or understand you, if you are suddenly letting all the repressed emotions out all at once. Or if you shout.

Maybe you have been the cool Girl for a little to long jebkinnisonforum.com/post/38962/

Together with the watertanks exercise you can push out with your hands and arms infront of you a couple of times. You can also push out with one leg at a time while sitting down (the same movement AS a baby uses to push itself out of the birthcanal) .

There is also some body postures you can do to feel the strength in your body - the wonder woman power pose among other things.

Being under lockdown together can also overwhelm a lot of people. Maybe you need him to go home to his own place for a while ?
If you are fa or ap it can make you very aware of the other person.

the good conversation model jebkinnisonforum.com/post/38078/

if he dosent listen you can use the broken record method

You ask if you should leave - fas can end things aruptly without communicating. Its like going from the green comfortzone and stepning out into the  red dangerzone. You are skipping the zone in between.

As someone with desorganised attatchmentstyle you can have  a lot of instinktive reactions which can be difficult to control.

You can take tiny steps and find out about your values, whishes and dreams. What are your needs in a relationship and what is your partners wants, needs and values in a relationship ? Are you compromising too much ? Are you getting drained ?

Hi there...welcome to the forums.  I am in  my early 50s and am starting to seriously work on my FA issues so it is never too late.  Obviously the best time to have this conversation is when you both are in a relaxed state....do not attempt this when you or he is in a hungry, angry, lonely or tired space because there is more of a chance for words to be misunderstood.  Start with what you appreciate about him....use I statements....Something along the lines of...I really appreciate how kind you are to me and my daughter and also the times that you cook for us as that gives me a little break.  I have however noticed that there are a lot of things that are left about and would really appreciate it if you could clean up a bit to help share that load.  I would also like it if we could share in the expenses a bit more as I have been really stressed recently about having to fund all the groceries etc. “. Something along those lines opens up dialogue and allows him to choose how he responds instead of being defensive.  It might be beneficial also to seek a couples therapist to assist with communications. 🙂
