Girlfriend not being intimate due to spending too much time together?

Me and my gitlfriend spend a lot of time together and we talk on the phone all the time, We dont live together but we spend time with each other everyday. A pparently due to all these things and her not having a chance to miss me because of the routine in our lives, my girlfriend hasnt been being intimate. She says she loves me and is attracted to me but i think she is to complacent and and doesnt feel the need to do the extra things that make me happy because she knows she will still get the same good treatment either way. Our life has been very minimal for the past few months and as a result it caused a lot of arguments and we did break up up for about a month and did get back together, but the intimacy still isnt there i know she isnt cheating or anything like that. But she doesnt want , I felt like devoting all my time and energy towards her was a good thing. But i guess to her its too much, mind you she calls me most of the time. Before i got with her i was in a music group, where all we did was drink, smoke bud, have with chicks, party and do shows. I actually really enjoyed the "rockstar lifestyle". But i met my girlfriend and i fell in love and put all that to the back burner because i respect her and didnt want her to have to deal with all the things that come along with it, so i decided to devote all my time and energy to making her happy. So now im confused i gave up my whole social life for her thinking it would make her happy and now its working against me. I know if i go back into the group it will cause problems in our relationship, but at the same time maybe she is right, maybe we are around each other too much so i dont know what to do now. Honestly i dont want to have to purposely not talk to her and see her just to make things intimate again to me it doesnt make sense, any suggestions ideas or opinions will help
