In love with employer

I'm 22, studying art and design and having a part time job as an art teacher.

My employer, which is also my art instructor, my mentor as well as the person which I fell for.

I had confess my feeling for him, and he hinted that he accept my feelings too.

We spend much time together at his home (with his parents around), cafes and sometimes short trips.

The most critical part is that we are 24 years apart.

We never let anyone know about our "relation" since I'm still a student .(But his best friend knew, and his dad seems to know, his family treats me well)

He is a wise man, conservative with his own style. We had been knowing each other for two years and he respects me and the "boundaries". (Never touches me, and we sits together with a gap between)

I do hope that we can still hold on for a couple of years before I tell my parent about us.

My family had been torn into bits when I first date with a guy in late 20's.  have no idea how my family could cope up with whats I'm in to.

Mom had been pressuring me to get a boyfriend.

Can anyone help me? I need advices. I want a happy relationship and a harmony family. I just wanted to do things right.
