<human>: I've been together with my girlfriend for almost five months now and I can't help but feel neglected. I've tried discussing the issue and she said she'd try more but almost swatted it off with the line "I don't like to show affection, but know that I love you, I wouldn't be together with you otherwise."

After that conversation, not much has changed. Everytime I try to connect with her, she gives me this look, as if what I just said (simple things like hello or "what are you doing?") was completely ridiculous or backs off as soon as I get close to her. This has led me to the point where I feel insecure everytime I'm with her and we just keep on in silence.

I still love her though, but I feel like I'm without it. I wonder if I should break up with her, as I feel the only thing keeping her from doing so is that she has a natural "way out" as I'm leaving for Argentina as an exchange student in the summer. 

I wonder if I also should continue until then, push through and see if things work out in the end and I may also avoid additional awkwardness as we attend the same class in Swedish high school.

I want to tell her how I feel, but I'm having trouble figuring out what to say to her in a way that it really sinks in that I'm not happy with things the way they are without her shrugging it off as just me being needy.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My girlfriend claims she has trouble showing affection. If that is the case, how do I approach her and try to make her more affectionate?
