He's Close To Losing Me This Year

I'm not sure how to cope with my boyfriend of 5 years anymore. We've had our ups and downs but it seems like we haven't been up in almost 2 months (since before Christmas).

We haven't moved in together because each time we get close, our arguments offset it and we decide to wait a little longer. The arguments have been increasing in size and it's to the point that I almost don't want to make up.

We are fighting about him going to Tampa for the Super Bowl. He's leaving on Tuesday and he didn't offer to take me (I'd pay my own way), he's going with 4 other (single) guys, and he's going to spend a bunch of money even though he's not buying a ticket to the game.

What really upsets me though is he's not going to even attempt to spend any kind of money on me for Valentine's Day. The last 4 years I've gotten maybe a dinner and flowers but it looks to me like he would rather treat himself.

I know getting to go to the Super Bowl doesn't happen often for most people but he does these guy trips all the time and WE NEVER go away anywhere together.

I blew up at him for going on this trip. He shrugged it off and thinks he can make up with me when he gets back but I'm not sure if I'll be around when he does. What should I do?
