<human>: My girlfriend and I were simply friends for about two months before we officially started seeing each other. I was very upfront about not being interested in a relationship, but that wasn't the case with her. 

Eventually, though, I gave in because she was really cool and I liked being around her. 

We've been together for three years and we still have lots of fun together, but we're incompatible sexually and I feel like it's beginning to really affect the way we interact. I love being with her, sleeping together, living together, etc. but I feel like I've never been an independent adult either. It's a huge convoluted cluster-fuck.

The more time goes on, the less interested in being in a relationship I am. Any ideas on what I should consider?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: GF and I were good friends, but after being in a relationship realized we were sexually incompatible (which is a big deal for me) and I wish we could go back to being friends.
