In love with flatmate, what to do?

Thank you all so much for the wonderful support and advice.

It didn't go down as I have planned but it ended amazingly. I was busy cutting up chicken schnitzels when he arrived home so the element of surprise went out of the window and just went with the flow and told him tonight I want to try out the new fondue my mom bought me for Christmas. He nodded and continued to walk to the patio and asked if we can do it outside since it so hot in the living room (*YAY!*).

He helped me set everything up outside and poured us some wine. It started out to be a bit awkward since we didn't know what to talk about and I just kept thinking when is that perfect moment to tell him how I feel?!?!?! After about 30 minutes of chit chat about our day I told him how lucky I am to have him as a flatmate and that any girl would be lucky to have him as her husband. He just smiled and asked whether I want some more wine...at this point I was screaming inside and could feel the tears building up wishing the night could just end. I honestly thought he blew me off!

He took all the plates to the kitchen and told me he is quickly going to make something for dessert. While I was sitting outside thinking how weird things might get in the future and how I will be avoiding him, he was busy making waffles with nougat ice cream and peaches with a brandy and sugar sauce (I think it's sugar melted in brandy). He served the dessert and sat right next to me taking my hand and told me that any girl might be lucky to have him, but he would be lucky to have me.

I laughed so loud feeling the tears run down my cheeks as he tries to wipe them off with a napkin. I just kept hugging him and didn't feel like eating the dessert as long as I get to stay in his arms the whole evening. He picked me up and carried me into the living room where we spent the rest of the evening talking about all those special moments we shared but never confessed our feelings to each other. I eventually passed away and woke up in my room this morning so I guessed he carried to my room lol

We are going to spend the day at the beach and have ourselves a picnic before going to my family, he really wants to ask my dad for his permission to date me :happy:

Question: I loved laying in his arms last night but would it be inappropriate just to have him lay next to me each and every night to feel his embrace?
