<human>: Provide a brief overview of the text.

So in February I'm going to San Diego for a business trip. I'll be there for about a week. It's a bunch of training seminars that get out at around 4 everyday. So after 4 I have nothing to do. My SO and I have been living together for about 2 months (dating 6 months) and I wanted to bring him a long. We both love playing billiards and there are a couple of places near the hotel where we could go play or he could go play on his own while waiting for me to get out. The hotel is also right on the beach with swimming pools and everything. Before I even told him about the trip he had suggested that we both try to get some time off in February just to play pool all week. I can't get time off yet because I don't have any vacation time until next April so that idea wouldn't work for me and we only have one car so it wouldn't work for him either. 

When I told him about the trip and how we would only need to pay for his plane ticket and two nights for the hotel (my work was going to pay everything else), he was excited about it and thought it would be cool. Even asked for the time off the next day. But here we are about a week after I suggested it to him, and now he's saying he doesn't want to go. That he would be bored. He sleeps in till anywhere between 9-11 on day's off so he would only have to entertain himself for 7-5 hours for 4 days. The rest of the days I'd be able to hang out with him the whole day. I reminded him about the pool halls and how he wanted to take a week off just to play pool too and he said that it's different then our normal place. Which I do understand. Most of his arguments is logical and I get that but emotionally it still bothers me a lot. I'm not sure why really. I also don't know why he changed his mind all of a sudden. I just don't really know what's going on I guess..
