Is it morally okay to live with girlfriend under one roof?

I am dating this girl for 6 month and most of the time we spend time together. But for the past few weeks my girlfriend suggesting to live with her because she cannot tolerate that in night I would go to my own home to stay and she wants me to stay with her the night so she can sleep in my arms and cuddle. I find it really cute that she misses me so I was also thinking that I will move in with her so she will sleep in my arms and after work she will sit in my laps and cuddle with me all my free time which I really wanna do it for her. But one muslim guy who lives beside her house told her parents that they should not let her boyfriend come and spend night in her home because guys who engages pri marital intimacy are bad guys, they uses girls for sex and ditch them the second the uses her body and by living together they want to satisfy their secual urges and so many negtive things about me. Yes I agree that a few times we hd sex but everytime it happened with her consent and I didn't used her body. If my intention was using her body than I would be harming her and using a girl for bas which was not my intention. First sex move was done by her, she really likes cuddle thats why I like to cuddle. I let her do her job, help her in financial situation and helo also her in cooking too as most of the time I stay in her place. I thought by moving in she will be happy s she will be able to sped more time with me. I just dont want to hurt her and I am not uaing her body for sex and if she says would not have sex with me until marriage than I would wait till marriage. Does having pre marital sex with her due to romantic attrraction with her and moving with her morally wrong and made me bad male?
