How can we stop arguing and saying things we dont mean?

I love my boyfriend to bits, and he loves me.. I treat him like sh!t because of some issues in the past and I do beleive in the saying: if you get with someone then you need to sto mention the past...

Well anyways, we keep argueing it over silly things...

like itbe half 9.. And he'd be shuting his eyes to be aslee and id want a cuddle. Or just over stupid stuff like im not giving him money for petrol.. Even tho its his car so why should I pay for petrol ??

And then it will turn into an argument after an arguement.. And ill say things like I dont mean, I just act like I dont care.. And say thing that I dont mean... Or say stuff with sarascium and I hate doing it... I fee so bad afterwords... Like yeastderday, he was falling asleep. And I was tiping water on him as a joke... And he got up and took the glass. And I went to fake punch as mucking about. And he tiped abit of water on me head, so I spat at him wot was way out of order.. I felt so bad for myself of doing that... I didnt mean to do it one bit... I cryed myself to sleep. After that, and when he got back in bed I was like all I wanted was a cuddle and you was going to sleep. He goes you went the wrong way about it. And I go well ill go get a cuddle of someone else den shall I... And I shouldnt of said that because he was like who who who.. And I was like who would... So the question is, how can I stop these stupid litte arguements and controle wot I say |
