Need Advice. Feeling choked

I am 28 year old woman and when my dad found out I was entertaining a suitor he got kinda protective and its kinda choking me . If I don't reply fast to his messages he would say "Who are you texting?" I'm like woah. My dad is kinda possessive. I know im old already, yet he kinda asking me questions that are not need of him to know. I have own job but i live with them since im not yet married . He ask me where I should stay when out home is renovated . I told him id like to stay at the first floor but honestly I'm thinking when in the future when I get married I'm gonna live in my own house not stay with my parents. Yet he still ask me. So i told him what he wanted to hear. I need advice how do I tell my dad not to control my social life. when he gets upset if i don't obey him. He really sensitive,wants me to follow all his orders., If i speak out my mind and tell him how I feel he feels kinda hurt. and makes me feel bad so i will feel bad telling him how I feel. Help please. Give me advice how to properly tell my dad that I feel uncomfortable being monitored with everything i do and whom i talk too. Your advice will be highly appreciated.
