<human>: Provide a brief overview of the text.

We've been dating for 3 months this Saturday and we've been official for about 2 months. She seems to be really falling for me. I've had questions about her flirty nature when I was with her and her friends. I'm just looking for some advice on how I can trust her since I don't really have a reason to doubt her faith other than her flirty nature that I observed and how she's told me a lot (how before we were official guys would text her asking if she was going back to the beach that year since they've hooked up before and how she had a fwb situation before meeting me). My previous serious gf of a few months cheated on me after a fight we had and she got drunk so I'm probably a jealous person now..
<bot>: Going away (26m), not sure how to trust flirty/hook-up gf (23F) that likes to drink with friends.
