<human>: Can you provide a brief rundown of the text in within 3 sentences?

I[19M] met my current GF [18F] 10 months ago and it clicked almost immediately, we started online-dating after 2 weeks and we knew what we got ourselves into.

We faced hardship and bit through it, we met each other after 6 months for the first time and after that every 2-3 months when one of us had time we would visit for about a week.

We decided earlier on last year that we wanted to spend this summer-vacation together for the whole 2 months so I saved up for it and we planned it out.

During these 2 months, after about 2 weeks I started feeling more dull and dull with the moment, like the flame that once burnt was dying for me, I know I sound a bit melodramatic but it's the best way I can describe it.

I started feeling more and more distant from her, not that she did anything wrong or that I found a flaw in her that turned made me turn away, it's more that I couldn't answer the love she was giving me.

I brought it up twice and we talked about it thoroughly and after all that nothing changed, I feel like breaking up is the only option for me at this point but I don't want to do that to her, I still care immensely about her and I don't want to hurt her.

I'm looking for any tips or help regarding this and/or a possible solution, whatever it may be.

Thanks ahead of time because I'm not sure I will stay up much longer, and excuse me for any bad grammar, I am not a native English speaker.
