How do I go this?? I really need help

So of course there is a lot behind this but I can’t explain it all since it’s a lot but I’ll try to explain the necessary.

Me and my husband of 2 years have had some problems but NO CHEATING. Only things like porn and lies but they don’t have anything to do with other people.

So the thing is that I am a person who always likes to talk about the problems, he’s no.

And usually im the one telling him we need to change I’m always the one that talks a lot and ask same questions repeated.

Since the first time we were supposed to “ get divorced “ it never happened we will fight and blah blah and I would get out the house for never left. Well that has happened many tunes either he says everything is over or I do and then nothing happens we still together.

I think the problem is that since he sees I never leave, he doesn’t believe me when I say that once I stop crying for him and caring about our marriage this is actually going to be over and all he says is take you Choice if you wanna leave leave if you want to stay stay ....

We both have agreed to change but for every little thing we fight and it ends up in “ I’m tired of this it’s over” but since it never happens he always says that ...

And don’t get me wrong we both have done things but they don’t have to do with my question ...

My question is how do I show him or let him know that he doesn’t have me for sure .... that I’m done playing games and the day I get tired I will be done with this. How do I get him to notice everything without him thinking I’m playing..... I want him to notice I’m serious and I’m done caring for this all the time but without telling him by words.

I want him to notice but with my actions if that makes sense and show him that not because I love him I will stay and hear him say it’s over without any action

He thinks he has me that’s why he doesn’t take things too serious when it comes to getting divorce because he thinks I’ll never go it. And if this keeps going I will but first I want him to see and if he does something because at the end I love him and he’s my husband but I’m tired of this
