There is no answer to this question. Think about it. If you want to have a party, your girlfriend must want all her friends to be there, but you don't. Because there are many people, it is not good to get together alone, so I suggest living alone, as long as it is warm, and it is best not to have big fish and big meat. Candlelight dinner is the best choice. Very warm and unique, you can go to the restaurant and order light music. . .
On the other hand, it is also beautiful to think of a reason to be apart from friends and be alone.
I hope it helps you.
