I had an amazing first date yesterday. We work together, and recently have been really hitting it off, so I took her out. We went to the zoo, got some food, she took me to meet her mom and her best friend, ended at her place with some TV and kissing. We get along great, and I'm really into her. She shows signs of wanting a relationship (calls me her bae/ boo/ love, posted on snapchat and instagram how much fun she was having with me), which is great. I'd love to go steady with her. She invited me to her little brother's birthday party this weekend, which is the same night that my buddies are throwing a gaming party at work. Should I go? I'm thinking about going, and then leaving after a bit to go to the gaming thing. Another question is, after how many dates should I ask her if we're together? I mean, she already acts like we are, but that was just our first real date.

Thanks Guys. Sorry for so many questions.
