<human>: Can you give me the gist of the text in a nutshell?

So I'm in a LDR with my girlfriend (was 10 weeks, now only 3 more weeks left) and I love her unconditionally but I when she does something small to tick me off, I want to "punish" her in some small way, sometimes its not talking to her for a day and she always asks what's wrong and I just don't talk to her. It gets sorted out after a day or so and we go back to being normal. We talked about it when it came up during a skype session and how she feels exhausted having to think about what she says before she speaks and how she seems as if she's always being "tested" .

I don't know how to stop, because the other night I asked her to tell me a story before I sleep and she said she's too tired and I'm just like whatever, said good night and hung up. The night before I told her a long bedtime story and she fell asleep midway. Small things like this make me a little mad. It's like I want to make her feel bad for not doing something for me. 

This "need" to do this has only happened after she left to go abroad for 3 months. I guess the pain of her gone makes me mad and want to make her feel bad. Like the other day, I told her I saw my ex and talked to her at the dining hall and chatted with her for 2 hours. I wanted to make her feel jealous (because she's the one that went away). Is this normal? How can I stop making every little thing she doesn't do or say a big deal.
<bot>: I feel like a asshole making my gf feel bad for things she doesn't do for me. Is it normal?
