yes it's fairly normal from experience. I haven't felt my twin flames presence in one week, and before that, a few months, then a year here and there. it's partly because of my own free will and desire to heal. I find that healing speeds up greatly when her presence is not around. it's like her presence appears all around me, then I'm set with motivation and drive to heal.

it's a blessing. I'm sorry you're confused, maybe you can try asking your guides or certain angels or God(if that's your thing) to shed clarity on the confusion. it does help. :)
