Unsure whether to break up or not

r/

TL;DR Me (22M) and 20F have been together for nearly 5 years now.

As of recently I’ve been feeling the urge to break up and i’m not sure why. Things the past few months within the relationship have been great compared to previously which is a positive but I just can’t help but feel that i’m not happy. I’m not sure if i’m unhappy with myself or the relationship?

We have been together from a young age and we have only “been” with each other if that makes sense. I don’t know if i’m a bad person or not but I feel like I might want to see other people. This girl is amazing and she is honestly my dream girl but for the future not the present, is that bad for me think this way?

I just feel like I haven’t got the fboy out of me since we have been together for so long from a young age and only with each other. My gf is going away for nursing placement soon and will be gone for a few months, I’m not sure if I need to break up or maybe spending some time apart would be good? Any help would be appreciated :/
