Freddie the Football Fan

Now, first of all, let's not judge Freddie by his name. After all, it's just a fake name; but it's not a fake story.
I was talking to a girlfriend about a month ago and she was lamenting over a recent development in her relationship with her boyfriend. They started dating about 8 months ago and things had been going fine...well, until football season started.
About a month ago they were watching a late night football game and she fell asleep. When she woke up, still on the sofa, at 2AM, he was gone. That's right...gone from the sofa, gone from the house. Now, earlier that day they had talked about going out after the game and she had said that she would like that. In fact, when they started watching the game she told him if she fell asleep to wake her up when it was time to go out.
She wasn't alarmed that he was not there. She figured that he probably went out to his local watering hole to talk about the game....or in this case, brag about his team winning the game. She went to bed, somewhat upset, and didn't awake until he came home at 4AM.
This was something they subsequently discussed...problem resolved. He would not do that again.
Last week they were watching one of the games on Sunday. This time it was his team playing against hers. His son, who is in his late teens, was there. Throughout the game Freddie yelled and cheered when his team scored or played well defensively, and griped and complained when her team scored or a call was made against his team. She didn't say anything about his poor sportsmanship or immature behavior because she didn't want to start something in front of his son.
When the game was over, and his team had lost (due to a bad call, in his opinion), he went outside. She figured he was just going out to blow off steam. After about 20 minutes she wondered where he had gone and she and his son went looking for him outside. He was nowhere to be found. A while later he showed up and said that he went to the store for cigarettes (although he had plenty). He had also told his friends that he would see them at the bar after the game, but after his team lost he decided not to go.
Question...is this just poor behavior on the part of a sore loser or does it go deeper than that? Should these behaviors be a determining factor in whether or not to continue the relationship?

Welcome!

I've finally gotten around to creating a blog. You're never too old to learn something new!
The purpose of my blog is to share and discuss experiences, ideas and opinions about dating and relationships. I know a lot of you out there are going through the dating process. Whether you're just getting started or have been there and are now back, it can be a frustrating and downright scary experience!
I had been away from the dating scene for 25 years and after my divorce found myself back in the dating world and scared to death! It's just not like it used to be. Online dating is promoted as a great way to meet your soul mate. If you have tried online dating you already know that it's not as easy as they make it sound. Finding a way to meet singles in the real world is not any easier; especially when you are 50+...the pickings are slim to say the least!
Please feel free to post any experiences (funny or serious), ideas, opinions or concerns about dating and relationships here! It's called "girl talk" but we're always happy to hear things from a guys point of view.
Thanks,
Annie
