I love him with my whole heart.

Janieaya
We both love each other, been together for 3 years now. Of course had our ups and downs but we still together. We plan to get married and have a family. 
It's just right now it's really hard for us because we're both 18 and live at home, his parents are very supportive but mine aren't at all, they don't want me seeing him. I'm still seeing him but it's just really hard.  How do I deal with this ?
