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

Like I said I'm only 22, and decisions like this are very hard for me. Especially since this is my first real relationship. 

The girl [H] is pretty awesome, she likes a lot of the same music as me, she loves cats, and loves Reddit. When I really start to think about our relationship though, it just feels like we're friends that live together and have sex a couple times a week. We don't go out much, she doesn't care too much for my friends or me hanging out with them without her included. 

About friends, she did have some friends a couple years ago in her hometown before she moved to college with me. I don't think she hung out with them very often though, and she doesn't at all anymore. So I am her rock, her only outlet. 

A couple months ago, we almost broke up. I broke down and told her that I think it needs to end, she seemed okay about it but pretty shaken. The next morning we decide to talk things over and try "one more time" and during the next couple months we would try to go visit family and friends more often to give each other space.  Well here we are a couple of months later, and I don't really see much change in her, especially not in her accepting my friends as an important aspect of my life.

So /r/relationships, should I just call it off and totally end it today? I'm sure I seem like I'm already going to do it so I might as well right? Well if that's true then I guess I just need some approval or disapproval from others. Help me reddit...
<bot>: I want to end my relationship of 3.5 years because I feel my girlfriend and I don't have the same perspective on what a "good" relationship is anymore, I feel we've grown apart.
