inconsiderate or I a nagging girlfriend?

My boyfriend of 5 months...

Really has upset me the last two Fridays.

Last Friday we had our first trip away together. It was only for a one night stay.

The night before he calls and ask if I want him to stay with me since we needed to leave early the next morning.

So I said yes, I would love that.

He was at a friends and says I'm about to leave....

another hour later. He's still there... says he'll finish his beer and leave...

Again, another hour.

Ended up almost 4 hours later, now almost 1am.

He shows up Wasted. Couldn't even put a sentence together.

Then was hung over during our one day trip.

Yea so I was mad.

And he told me I needed just accept it. He couldn't change and to not kill the weekend.

Now it's Friday again... I'm having a yard sale.

He said he would come help me.

He stopped at his friends house. Called said he was about to leave.

Another hour goes by, I call. He's still there.

He still needed to go home and pick up the dog.

So now it's almost 7pm when he said at 439 he was leaving.

Am I crazy? Am I wrong?

Makes me want to leave him.

I don't care that hangs with his friends. Just don't say I'm about to leave because I sit there waiting
