Break up and children

I am writing with the hope someone can advice me whether or not I should stay in my relationship. My partner whom I have 2 beautiful boys with (6 and almost a 1 year old), has been overcritical in everything I do, I will give some examples: the car is too dirty, our son didn't too well at football, he wanted the glass cup instead plastic, when travelling abroad because they drive on the right hand side etc....... It's like walking on the egg-shelves all the time. I kicked him out some many times and feel very stupid I gave him another chance. His mother also left his father because he was the same and he -my partner knows exactly why his mother left his father but he doesn't want to acknowledge he is the same. When he starts his criticism he would push me until I shout and then he puts all the blame on me. It break my heart because we have 2 boys who I love the most in this world and I don't want them to go through this any more especially the older boy who already understands what is happening. How can I approach my partner to tell him either he changes or this is it? Would the separation be better. I can not stand this any more. each time this happens I get tummy ache and I get very nervous. I will be very grateful if any one gave me advice what i should do? Thank you

Tell your partner that if he has another problem he can fix it himself. You need to leave this guy for good. The way he acts is not good for the children (In fact, by staying with your partner, you are subconsciously saying to your children that this is okay behavior in a relationship…). You don’t have to walk on egg-shells because it shouldn’t be necessary. He has no right to treat you like that. The fact that you are still with him enables his behavior, and it will continue, whether you like it or not. There is no changing him, he is who he is. Ultimately, he chooses who he wants to be. Make sure to tell him that the only one he needs to worry about criticizing is himself, and that he can get his own glass cups. TILES P.S. If you break up with him, do it for good. Do not take him back again, because he is not good for you.
