Need some outside advice!

I'm not really sure what or why I'm doing this but I just needed to hear an opinion of someone that was unbiased of my situation. My bf and I have been together for almost a year and living together almost five months, we have struggled over the discipline of my kids, they can be a bit overbearing at times. And yes I take full responsibility for that, I'm learning how to get that under control now but nonetheless it has taken a toll on our relationship and my bf feels I have "stabbed" him in the back by disagreeing with him in front of the kids when he said it was important that we shouldn't. And by habit of always sticking up for the kids I jumped in and took up for them and now he wants to end our relationship. Is he overreacting? Or did I do something wrong? Please help me understand!

Though the situation can be avoided, very often it does happen when the kids are involved. Its motherly nature to protect the kids and you were acting on natural instinct. But having said that your BF is acting on his natural instinct. He doesn't and won't understand it. I feel may be you guys should come to an understanding through mutual discussion. Ending a relationship over it would be silly.

yes agreeing with Shivangi, there is always a way rather than to apart, find out some way , have a good discussion, give some sorts of surprise and make him feel important and tell him importance of him as well as children to you.
