How Hard is it to say I'm Sorry?!!

my Usually wonderful husband was being an Ass last night! we went over to our friends house last night to cook out and spend time with them and their daughter. We had such a great time and I let billy drink and I drove home. Well we didn't get home last night until Well actually This Morning around 1;00 am. Both kids were exhausted and so was I. Billy was Well (Very Well) Lit and had fallen asleep on the bed as soon as we got home. I got Both kids in bed and ended up laying down w/ shelbie for a few minutes because she was to tired. She was just crying and whining so I laid down w/ her till she fell asleep. It took me Forever to get Billy wake enough to get up and change clothes for bed. Then he had it in his mind for a little " Action" *wink wink* and i'm like Hell No! I'm Exhausted. So he gets all Huffy and decides that he's going to go down to our Other friends house who lives right down the road from us to Pitch Horseshoes. Ummm What?! At 1:00 AM?! I told him that that was stupid and Why would he want to go down there now?! Just cause I didn't want to have Sex doens't mean you just automatically take off! He said that he'd been planning on going down there Anyway all day! This just Pissed me off Royally! And he told me to stop Being a Bitch. I told him that I have the Right to be a Bitch every once in awhile! He got ready and came to bed and I just laid there till I feel asleep. I HATE Fighting with him! we hardly ever fight and when we do I apologize. But he Never! Never apologizes to me! Ever! He complains all the time about not spending enough time with me & the kids and then Yesterday he has them for about 2 hours, comes home and then Leaves saying he'll be right back. and then comes back 4 hours later! I know he's not up to no good. I Totally trust Billy but he gets side tracked helping his friends or cousins or whoever and we get left out. He's working today and I didn't get to talk to him this morning before he left. I'm hoping adn Praying that he's in a good mood this afternoon. An Apology would be nice too. Yeah right. Not holding My breath on that one.
