Parents making me move...

So I am 21 and for the past 3 or 4 months I have lived with my boyfriend who I have been dating almost 2 years. We are so in love and want to get married someday, but just aren't financially ready yet. My parents do not believe in living together before marriage. My boyfriend asked my dad how he felt about me staying there and my dad basically told him that him and my mom don't approve so my boyfriend said I need to go back home so he can respect my parents which makes sense, but I'm just really upset because I was so happy living with him. I feel like they are making decisions for me and I'm just so sad and angry.
