<human>: Can you summarize the given text in a few sentences?

So this girl and I have been flirtatious for about 6 months, until recently when we started to be more in an open and physical relationship. The main reason I had for not initiating things earlier was because of the small sized friend group I am in. I didn't want to disrupt the peace. (Just a little background.)

So we were texting a bit and she seemed pretty down so I decided to call her instead of just text. We talked about what was going on in our day and such, and after about 20 minutes I just said
"Alright, I'm going to hang up now."...... .-.

Why the fuck did I do that. It's not even that I didn't want to talk to her, I just decided that was the right thing to do. I guess I thought there was nothing much else to say? I'm just pissed at myself because I have a pattern of being a shitty guy without knowing until seconds after I have a chance to help it. This was mainly a rant because I am really distraught at how I acted. What I said had no connection with what was going on in the conversation, but I said it anyways ughh. The more I think about it the more I feel my soul drifting from my body.
<bot>: Embarassing moment where I told my love interest I was "going to hang up now" really abruptly for no apparent reason. Feeling awkward, disgusted with myself, blown away at how stupid I am sometimes.
