Losing virginity!

I have been with my boyfriend for a year now and I am still a Virgin before I was with him I was in a toxic terrible relationship and I was completely attached to my ex, I have been holding off having sex with my boyfriend who I know loves me and cares about me he treats me how I should be treated but I haven’t had sex with him because i am scared I will get attached again and be in a illusion again and also because my parents really want me to wait till marriage I am an only child and i feel guilty.
