<human>: So basically I met a girl in the beginning of the semester during our orientation week.  She caught my eye the first day and we ended up talking on a bus ride somewhere and clicked.  We exchanged numbers and continued talking.  

Fast forward a weekend and I actually start texting her (during orientation week we were in the same group so saw each other everyday) and have quite a long conversation.  We continue texting and I eventually ask her to hangout (eat) which she agrees to.  We go to an ice cream shop and me being a dumbass forget to pay for her, but she didn't seem to mind.  We talk for a good 3 hours, losing track of time, and then I dropped her off back at her dorm and there was that.

I text her at least once a week and we have lunch together at least once a week for the last six weeks.   

We have different majors so the only time I see her is when she is walking to her class (small school) and our weekly lunch. Though I ask her if she wants to do something almost every weekend but since she is a is a D1 athlete so she doesn't really have a lot of time on the weekends due to that and homework. Either way I still ask just because.

Overall, I really like her and I feel that through our conversations she does the same. I've been told that because of our lunch deals and me taking her out twice we're basically together, but I want to know for sure.  

Oh and I haven't been in a relationship or had a thing with someone before and she doesn't know this.  I have no idea what I'm doing.

Summarize the given text in a few sentences.
<bot>: Been seeing/talking to girl for more than 3 months. Have taken her out twice and have lunch weekly.  How do I ask her to get official/serious?
