Was he made this way or is this his natural personality?

I started dated this guy and he is
1.way too materialistic (I'm not talking about iPhones, I mean expensive, luxury cars, expensive clothes)- he doesn't just want these things. His life revolves around them
2. He's way to conceited/arrogant. (He's way past confident.)
3. He drinks EVERY single day.

My friends and family keep telling me he's no good and low key depressed and mean but I keep trying to find the good in him.

What I'm really asking if someone made him this way or he's just naturally like that. Basically, is there something hidden that I need to watch out for?

1. If he is rich and can afford it then why not? If he isn't rich, everyone wants what they can't have.
2.self love i believe, is born within. No one can make you what you are and are not.
3.he's an alcoholic, its a tough habit to kick and most never make it. If he isn't rich, unless you want your kids to starve - get rid of him.

WOW! I feel as if your dating my ex lol. My ex was exactly like that and even worse. He had to have the latest everything and always felt like he was on top of the world. He had a huge ego and always insisted he was right and never admited when he was wrong. Even when he was wrong he could never directly apologise, and always found a way to apologise that doesn't directly point the blame at himself and could somehow turn it on me.

He wore exspensive things and looked down on me because I wasn't up to his taste, he tried getting me to wear expensive things and enjoy his luxury lifestyle, but it just wasn't me. You need to watch out because like my ex, he may start becoming controlling, where he told me what to wear, what to say and how to act around other people in a really patronising way. He probably never loved or even respected me and had I not got out of the relationship, he may have become abusive due to HIS excessuve drinking. I always tried to find reasons not to break up with him because I wanted it to work, but I'm so glad I saw sense. Listen to your friends and family, they care about you and want what's best.
