<human>: I come to you guys seeking help, my problem has been eating away at me, for a while - but recent events have seemed to worsen my situation. 

Ive been with my gf for 4 years, we live together and both love each other. However, we both agree that we are both getting a bit tired, due to spending all of our time together. We have no friends and no hobbies due to living in the middle of nowhere. We are the only partners we have each had, but I want to sample new things, brought about by getting a crush on someone I work with.

However, my main problem isn't ending, it's that I can't end it in good conscience.  I feel invested in her, as she paid my way for a few years and I have also helped her through a lot of mental issues,  so I worry she would decline, and I dont want to be responsible. Also when ever we attempt to talk she ends up crying and gettig extremely distressed.

Any help or insight would be amazing!

Can you give me a shortened version of the text?
