Yes I am not lying when I say this.

My girlfriend is mad at me for no reason

Let me give you some background information. Me and my girlfriend are 18 and we have been dating for about 8 months and a half. Trust me, our relationship is very very healthy and we are always so happy and having fun with each other. We have both openly voiced our opinions and thoughts about our relationship throughout these 8 months and we are always so happy to hangout and to talk to each other. We are also both very very understanding so we really don't have fights but instead we will have disagreements or when ever there is a time where it is acceptable to "fight", instead of fighting we just both openly talk about what happened and we move on from it. We are both very very happy together and we both are very similar and many people have told us that we are for real perfect for each other.

But now to tell you guys what has been happening. So we are both still in Highschool and last week we got off of school for christmas break. And she got grounded for 2 months because she had 2 zeros in one of her classes. Now yes it sounds very stupid for her to do that and it is if you don't understand the context. But that doesn't really matter what happened, just know that she is grounded for 2 months and she won't have her phone nor will be able to hangout with anyone nor has her car. So yeah we are both pretty upset about it and its really sad because we had so much planned for this break. But luckily, she found her old phone and she has been using that to text me. She always seemed very upset to text me and it was very easy to notice that although she wanted to text, she really didn't feel like it though, if that makes sense. I finally asked her about it last night over the phone and she said "Yeah, this type of thing has happened before in past relationships with my dad and my ex (her parents are divorced and her ex thing is very complicated)" She then goes on to explain that yeah it some type of "crazy" thing she has she guesses. So its not happening just because of me, like it has happened before in her past.

She explained it like, she is upset that we can't hangout and because we can't hangout she gets frustrated about it, and then somehow she gets upset/mad at me that we can't hangout. And yes, she knows she has no reason to be getting mad. She has told me she doesn't know why she is getting mad/upset towards me because she has even told me this. Like she honestly has no clue on why she is feeling like this.

We have tried talking about it and it truly seems like she has no idea why she acts like this. I am very good at seeing when she is hiding something from me or upset or lying. How she feels translates into text form very noticeably.

Does anyone know what may be a good solution to this?

I will answer any questions to help find a solution, I just really don't want her to be mad and upset at me because it has been ultimately hurting me and her. Basically it hurts our relationship and we are both afraid that it could severely damage it.

Thank you to all.
