<human>: We have been dating for 2 years and i often find myself bored with the relationship and thinking about other woman. I have tried talking to her about it before but all she does is cry and make me feel like an ass. I grew up with 5 sisters so i hate crying woman. She is also a senior in high school and involved in more drama that i just dont care about. 

We have gone on a few vacations and they were fun for the most part, sometimes spending longer periods of time with her drives me nuts. I just dont know what to do. 

I truely do care for her but sometimes she makes me more angry and crazy than happy.

Could you distill the essence of the text into 1-3 sentences?
<bot>: i have grown bored, what should i do and how can i explain this without being an ass and making her cry?
