how do you know you should end your relationship?

in addition.. how do you tell your long time life partner you want to seperate? (we're together almost 8 years, we have 1 child together, combined bills etc)

I am pretty sure I want to leave. It's something I think about almost every day now.

I think I have put up for too much for too long and I reached a breaking point. It's not like I never addressed the issues, he just never really took me seriously. Now he had a wake-up call, when I opened a private account.. and I feel that he's taking more into consideration but is struggling with the fact that I am a person with my own opinion and he can't always walk over me like he's done always.

he's struggling but trying.. but then again.. I had my breaking point and I don't really want to continue.. but I'm also worried I'm making the wrong decision.
