<human>: Could you distill the essence of the text into 1-3 sentences?

I've been with my girlfriend since I was 19. We are both eachothers first serious relationship. It's been good and it's been bad like most relationships, but i can't seem to get over the feeling that I'm missing out on so much.

This isn't me trying to justify wanting to go be with other women or anything like that. I just dont see myself being with her for the long run and i feel like im wasting my time. I recently came off a really bad episode of anxiety and depression but i got professional help and im doing much better.

We recently took a 2 week break and it felt pretty amazing, no worries and not having to deal with another persons stresses was great. So is that what i feel like when im single? If so I want it.

But then i think back to when i left her before for about 8 months. All i thought about was her and i went back and fell again. I dont know im stuck and need some help and advice.
<bot>: Want to feel the feeling of being alone/dont see myself with her for the long run. Scared im making a mistake.
