Girls, My girlfriend blocked me after an argument last night. How long will it last?

[Rome9]

So last night while we were on Google Duo, one of her friends text her and asked her if she wanted to start going on walks at the lake on their lunch breaks (they both work from home.) I made a sarcastic comment, "I've been asking you to go for walks forever, but whatever." Then I continued to pull up the show we were about to watch together and squinted and joked about not being able to read the TV. When I looked back at her she was pissed. She had replied to my comment about its about to be spring and not cold like when I wanted to walk. She argued with me that I said go to Lake, when actually I was talking about a walk in general. Anyway... she got so mad at me for not replying to her response. She then told me to get off her phone and when I said ill talk to you later, she stated that no I won't because she's blocking me. Next thing I know she hangs up and minutes later I get a message on FB Messanger by her "Blocked." We use Messenger to send pics and meme since I have an android now. Anyway... I don't understand why she got so mad and I'm wondering if she'll unblock me soon? Thinking of having a bottle of her favorite wine delivered when she's off with an apology note.

If she's blocking you & not talking to you over this stupid shit, she isn't mature enough to handle a relationship.
You have every right to say, "So your friend wants to do it, you go, but when I want us to do it, you don't. That makes sense"
She's just pissed you called her out on her shit.
If my boyfriend did this to me he would be gone, I don't play this "I'm blocking you" game.
It shows me how fucking childish you are & I'm not looking to be with someone who acts like a 5 year old.

She seems kind of childish. Can you not text her regularly? If so then text her and let her know that you don't appreciate the childishness.
