<human>: Hi, we've been together for 2 years already and I feel that we're growing apart and that I don't appreciate her as much as I used to.

She's a cool person, she is beautiful, and we fit nicely, but I feel that we're more like friends. I don't feel attracted sexually to her either.

It's been a long relationship that included a lot of fucked up things that we managed to get over them together but I feel tired of the same issues reappearing everytime.

Things have changed a lot in our relationship and we are spending more time fighting than having a nice time together.

She's in a stressful part of her life, she's preparing for the equivalent of SAT exam in my country. Breaking up with her would definitely affect her results, and she needs bigger grades to get accepted at an university in Germany.

She'll finish all the exams around September, and I really feel like it would be very hard for me to stay in a relationship in which I lie to her about our relationship.

She's a nice girl that didn't do anything bad to me and I wouldn't like her to fail her exams and not get accepted in that university.

What can I do? I feel like everything got old.

Can you summarize the given text in a few sentences?
<bot>: My girlfriend needs my emotional support but I don't enjoy this relationship anymore, but at the same time I wouldn't leave her in order for her to get over this hard period of her life.
