In a relationship, when do you just give up?

Thanks for the comments. I think the problem is he wants me to understand how he feels but when its something that bothers me, im just supposed to overlook it and go on. I have a few friend girls who say their men do the same thing so i think its more of a man thing than anything. Im just to the point of giving up the almost 10 years and letting it go. There is nothing more i feel i can do and i am sick of arguing all the time. Then when i try to do that, he always comes back begging. Last week i had company and he came and knocked on my door and seen dood sitting on my couch and lost his mind. And im like "Why?". You act as if you dont care and we argue all the time and then we agree that we should go our own way but when you see me with someone else, you cant handle it. And if thats the case, treat me the way i need to be treated when your with me and we wont have this problem. I think he is finally starting to see that i am getting to the point where i dont care too much, it is what it is and im not fighting for it anymore. If its meant to be, it will be. If not, its not. There is nothing more i can do. I love him alot but as time passes, im just like whatever, have it your way but without me. You know? Im getting too old for this.
