<human>: Hello r/relationship_advice!

I'll try to make this as brief as possible. I've been with my long distance gf for 1 year and 8 months now. We haven't met yet but were planning on meeting sometime next summer. We've cammed and such, so I know she's real..Anyway, that's not the point.

In the beginning (about 6 months into the relationship), things were amazing. I couldn't have been happier. But then things went downhill a bit..I can't name all the reasons, but she would and still does get angry at me over little things, or anything in general..I've been feeling like I'm the only one who made an effort to try and solve our problems when we fight.

She also doesn't know how to handle things when I'm upset..I've pointed this out to her and she gets upset and says she tries but I don't see it. Now that I look back on it, it doesn't seem like she's there for me..not because she doesn't want to be, but she doesn't know how to be..

But recently, I've been feeling really alone. Even if we're talking on Skype, I feel like she's not there..I miss her even if she's sitting there. And she hasn't done much to try to help either..like I said, maybe it's because she doesn't know what to do [she's really really oblivious]..but it hurts so bad..it hurts worse that she doesn't try.. I feel like I've lost my gf who I was happy with and that I'm just with her because I still love her..not because she's a good gf.. I'm already feeling alone and I'm afraid breaking up with her will make it worse. I haven't been single since I was 15 years old so I don't know what it's like to have no one to talk to whenever I feel like talking. What do I do?

Can you succinctly summarize the text in 1-3 sentences?
