Does my girlfriend love me still?

when ever im with my girlfreind it seems shes staring off and whenever i hu her i feel her hugging but it feels as though she doesnt want to hug im not sure if my paranoia is ust messing with me or if she doesnt like me anymore, another thing is she never likes to talk on the phone its only text messaging but the gaps inbetween my texts and her replies can last for hours or so. is it me or does she not love me anymore?
