Hey guys, need some advice on this...

My GF of 9 months has a habit of not finishing her drinks that I make for her when she is at my house and we are just chilling.

At first it was something I would just tease her about but last night I picked up club soda and limes because she mentioned this drink that she wanted to make. I made it and tweaked it to wear it was good (used two shots of Belvedere in a tall glass and some other stuff). Sure enough, she drank about half of it and then left the rest.

This morning I questioned her on it and told her that going forward she should make her own drinks from now on, which made me kinda sound like a dick, so a couple minutes later I clarified to say that she could still drink my booze but this way I wouldn't potentially screw up it up and she could make it the way she liked it. This resulted in cold shoulder SPAM.

The thing that I don't get is when she's over at her friends' houses she drinks several drinks no problem, it seems like there is some hang up that she has that she wont tell me about when drinking at my place.

Like I said at first it was no big deal and something that I would tease her about but it does seem like there is a legit underlying issue.

Is this normal? Anyone else experience this?

Any advice much appreciated.

Thanks!
