<human>: Summarize the given text in a few sentences.

I have been seeing a girl for about a month now. We have introduced each other to our group of friends (she has even brought me to meet her mother and grandmother), have gone on numerous dates, slept at each other's houses, PDA when were out, talked about dates a month or more out, chat daily, have had sex once and oral sex many times. 

I am nearly a year out of a 9 year relationship and back in high school when I was single we had to find some clever way to ask a girl out in order to determine exclusivity. My question is: do I ask her to be my girlfriend? Do I have to "ask her out" as it were? Or do I just ask her if we are exclusive and see where the conversation goes? This is all very foreign to me. I've done it like two or three times in my life and that was back when the label was more of a cliche. My goal is obviously to determine that we are exclusive and I am sure we are at the moment based on how much we talk and see each other, but I don't know how to approach the conversation.

Any advice?
<bot>: Do I have to "ask her out?" or is our relationship habits enough to determine that we are officially 'dating'.
