I've got a lot on my mind and i definitely need some advice. I'm just gonna start typing and hopefully it all makes sense by the end... I'm 19 and have been in my current relationship for 2 years. My girlfriend is my best friend and i've had the happiest moments of my life with her. On the flip side, i've also had the most upsetting and angry moments too. I find that lately i've been getting very frustrated and drained by this relationship. I sometimes find myself ending one of our tough nights with sincere urges to just leave her and never look back. By tough nights i mean a bad fight or simply being annoyed by her dependency on me(she has very unreliable friends/family). After these nights i feel like i would be much happier without her but find that i change my mind once i cool off. This girl is my best friend and a huge part of my life. I feel that i love her but do these frequent doubts mean i shouldn't be in this? I'm so torn! I often want to be single for a change but i care for her too much to ever leave. I worry most of all about deciding to break up and then regretting it after the novelty of being single wears off... Another question, mostly directly towards those who have been in long term relationships: Do you have the urge to be with other men/women while in a loving relationship? I find that when i'm out with my friends i want nothing more than to just go pick up a girl at the bar, i miss the spontaneousness of doing something like that. Do feelings like this exist in a loving marriage? thanks for letting me vent, any advice or opinions are more than welcomed.
