<human>: So I be been in a relationship with this girl for ever a year and things were going for for the most part. We've learned a lot about each other and ourselves this past year which is a good thing. 

Recently, however, she has changed out of no where. Her libido is completely dead and gets mad if I say anything sexual even as a joke. But that's not my main concern to be honest because my libido has been killed with this: one day when we were on the phone late at night and I said I miss you. I hadn't seen her in a couple weeks and she had started work and college so we've been talking less and I wanted to let her know I missed her. To my surprise she says I say that too much and I say I love you too much and basically wanted me to say it once in a while, but neither of us has really said it since. That was a couple weeks ago. 

This week it was my birthday and I invited her over to a small gathering at my house and she said she'd come. However it was already getting late so I asked if she was still coming and she snapped on me. She said she can't be with me 24/7 and that I should just go look for a girl that can because she's tired of trying to make me happy. The weird part is I haven't seen her in almost a month so I was really confused. At the end of the night she texted me she missed me and that she was sorry. Also, I'm not the clingy type. 

So what I came here is to ask is if I should break up with her because I'm really confused. At times I feel like I should and it's hard to find feelings for her anymore after she told me to basically stop saying I love you and I miss you. I know I'm young and that there will be other girls and stuff but every time I see a picture of us or just her, I get my feelings back and I feel like I love her and its hard to lose ALL feelings after being in this for over a year. I just need advice Reddit. Sorry for the wall of text

Can you succinctly summarize the text in 1-3 sentences?
<bot>: my girlfriend seems to have lost interest in me but says she still cares and I lose interest in her except when I see her or a picture of her.  Don't know what to do.
