I want to seperate from my partner of 10 years.

[Anxietyqueen1987]

I want to end things with my partner, I've felt like this for a while and the relationship is actually becoming unbearable now.

A bit of back story, we have been together since I was 22 I'm now 32 and feel I have grown up a lot in that time and that my feelings have started to change. We have a daughter together and I think the only reason we are still together is because of her. We constantly argue, he's constantly angry, there is also no progression whatsoever in our relationship and I just can't bear it anymore. I have told him how I've felt before but he doesn't seem to take me seriously, he just thinks I'm being dramatic - how do I get through to him that I want to end things for good?

It’s really tough to address by yourself especially if your dp shows resistance.
I’d write down what you want to say. No waffling as things get lost amongst it.
His reaction will give you your next step.
If he denies your view point then insist on couples counselling together. The counselling will be able to help you separate more amicably and allow you both to express yourselves in a balanced way.
