Why do they get upset when they get what they wanted?

So back to me and the boyfriend...neither of us have been in a relationship in a while and there's some adjusting going on. Well he freaked out on me a couple weeks ago. Went off on me because we had plans for a Friday and then he told me he couldn't come. Ok..I asked what changed..out of curiosity. I can adjust with the flow. Well he went off about how we'd been spending every weekend together and OMG he just needed a break. What's the big deal? And he put off seeing me for about 10 days. hmm.. fine..well in that time I found things to do with my friends. Hey, I had a life before you and I can go back to that if you don't get your head out your ****! Well I went out to have a few beers with a girlfriend of mine that weekend. And low and behold he was a little jealous I think. So ok... you don't want to see me but then get a little miffed because I go out with the girls? Uhm..newsflash. You wanted time to yourself. Well this is what I do with time to myself. AND then this week I asked what he wanted to do. He said he didn't know yet (and in fairness he is remodeling a bathroom after is sprung a leak). I offered my help and he said he'd let me know. Well, friends invited me both Friday and Saturday night to go do something fun. So I accepted...and he got hurt. Well.... you are thinking I'm just going to sit around waiting for you to call? Remember that whole you needed more space? We were spending too much time together? Well now we're not spending as much so it's an issue? So why are you getting upset if you're getting what you asked for? Somebody please clue me in!!!
