<human>: Can you condense the text into a few key points?

I have been dating this guy for a year, and he is really nice and has been really good to me. 

The only thing is I have never been to his place before, he would always make some sort of lame excuse " mom is working, mom's cleaning the house, it's dirty" next week and it's always next week. 

His mothers birthday party was last week Saturday and he wanted to take me as a date to it. The entire week he was stressing hardcore 

What does you dress look like, what type of shoes will you be wearing, how will you do your hair, be on your best behaviour it was really starting to get on my nerves. 

Saturday afternoon he came to pick me up (there was some guy driving the car), and you could see he was stressed out of his mind. I made a comment about how posh the neighbourhood we were in was and he let out this nervous laugh. 

We pulled up to this borderline mansion type place and he turns to me and say's dont make a big deal but this is my place. 

In short I learnt that his parents are very wealthy and he has been hiding this from me, he hides it from everyone. It's like he see's it as embarrassment rather than a privilege. 

The whole night he spent walking around talking to these guy's in suits. They seemed very posh and to be family friends with him 

When we went to his room later on that night, I blasted him for not telling me about this for a year. He has basically been living in the lap of luxury and we have to hang out at my place. 

Am I overreacting about him not telling me about this? or is this a minor thing that is normal to keep hidden
<bot>: Found out my boyfriends parents are wealthy, do I have a right to be mad that he was hiding this from me?
