Is asking for space in relationship wrong?

I am in relationship after 7 years of my breakup. I have to speak to her all the time if not we will get in to arguments. either i have to be in video call or regular call when she is away from me. I give her space when she hangout with her friends. IF i hang out with my friends she will make number of calls and ask how long i will be there with them all questions. I have to be on call when im cooking i have to be on call when im listening to my favorite music i have to be on call with her no matter what im doing. Im not getting my space. If im not in conversation with her she says i think you dont love me as much as i do. She takes the this conversation to the stage of i get frustrated and irritated and she says im afraid of loosing you i never met a guy like you. Im confused. I dont want to do my love life like a duty it has to be a responsibility.
