I (26F) Awkward tension with bsf (26M) after getting drunkAwkward tension with bsf after getting drunk

My (26M) friend and I (26F) have known each other since last 8-9 years. We share a very different and beautiful space with each other and are literally each other's 3 am friends. We both are single currently and can't say about him but I've never seen him anything more than a really good friend. He knows that too and none of us has ever given mixed signals/hints or something to the other person. We both have dated other people in the past and have seen each other in all major events of life. Nothing weird/awkward/romantic has ever happened between us. Although we speak to each other daily, we hardly meet once in 2 months.

Yesterday we met and spontaneously decided to get a drink (we've never drank together before). We had a few drinks (none of us was too drunk) and were sitting and talking in the car. It was a nice mellow tipsy kinda situation. There was this sexual tension in the air which I'm sure he could also feel. He hugged me and mentioned that he likes me since forever and finds me beautiful and would want to marry me. I don't know why but I felt a little something after he said that.

I'm sure we would have kissed if one of us had initiated it. I started calculating the pros and cons of making out with him in my head and I'm sure he too was doing the same because nothing happened but those eye contacts and stares were speaking a different story altogether.

We had so much fun together, literally screamed in the car singing weird songs and then he dropped me home. We spoke normally in the night not mentioning anything about the day.

I've been overthinking the entire situation in my head again and again. He had to leave to another city today and will return after 3-4 weeks. I know we won't be able to speak properly.

I'm confused about the entire situation and don't know how & what to talk to him about?

Please help!!
