<human>: Give me a shortened version of the text

Long time lurker first post etc! So I've been dating this girl since the beginning of grade 12. First serious relationship of mine. We have been living together for almost a year now. I feel as if we aren't the perfect match for each other in terms of interests and what we like to do on our spare time together (I like to hike and go do exciting things vs Netflix and relaxing). Also, ive noticed we don't have really interesting conversation. 

I'm starting to ask myself "is the grass greener on the other side"? It's hard to settle down with someone when you haven't really explored 'outside of high school dating'. Maybe there's somebody else who clicks better with me? Maybe I'll be happier with someone different? It's a hard thought to shake. This is what really set off my thoughts:

I recently got a tattoo and the artist was 2 years older than me. We spent hours together and we clicked so well and had deep but easy conversation. The energy was so real, I never have that connection so quickly with anyone else. Not to mention she had an attitude about life that I admired aswell as very attractive. 
Has anyone experienced this?
Is it worth it to throw away a 4 year relationship for these curiosities?
