24M kissed 24F best friend after 13 yrs; now staying alone together, confused

[Varun]

My best friend (24F) and I (24M) have been friends for over half our lives. It's always been completely platonic and we never crossed any boundaries.

A few weeks ago we were at a house party. Both of us had been drinking and we stepped out to the balcony while I smoked (she doesn't smoke but she usually joins me). We were having some flirty chat - which isn't unusual for us - and a romantic song started playing downstairs. We kept exchanging looks and, out of nowhere, we kissed.

It wasn't an intense make‑out, just a quick kiss, maybe 10 seconds. But it happened.

The next day we brought it up once, acted pretty chill about it and then moved on.

Now my flatmates are leaving next week and I'll have the place to myself for a week. I jokingly told her she should come over, stay the night, we'd drink and hang out. Without hesitation she said, "Of course I'll be there. Who else would I be with?"

Now I'm nervous.

We kissed while people were around. What will happen when we're alone all night?

We've talked before about possibly being a couple, but we've always feared risking a 13‑year friendship. The risk/reward feels huge for both of us.

Part of me feels I should talk to her about how I'm feeling before next week. I have a strong feeling she feels something too. But if I don't bring it up and something happens when she's over, then what?

Do I have the conversation beforehand, or am I overthinking this?

TL;DR: My female best friend and I have been close for 13 years. A few weeks ago, after some drinks, we unexpectedly kissed. We brushed it off, but now she's coming to stay over when I have the place to myself, and I'm wondering if we both have feelings. Not sure whether to talk about it beforehand or just see what happens.

Probably sex... use protection and take it slow.

[Nakul]

Just go with the flow.

[Madhav]

Friends with a kiss.

[Sagar]

Whatever happens will happen when you're alone together.

[Riya]

Since it's a 13‑year friendship, I'd usually say go with the flow, but it'll be a bit more complicated. Don't let fear block the change - the kiss already shifted things, you can't ignore that. Have a mature conversation before anything too intimate happens. If you're confused, don't let heat drive you; be honest (learned that the hard way). I'm about 99% sure you both like each other, so enjoy it, you crazy lot.

[Shruti]

Don't overthink it, just go with the flow.

[Chandan]

Just go for it. She's definitely into you.

[Arjit]

But friends don't know how you taste... lol. Good luck!

[Mohit]

Please let us know what happens.

I think you'll be fine. Talk to her when she arrives - it'll take courage, but setting intentions will ease the sexual tension building up.

PS: My best friend and I had a similar drunk make‑out 7 years ago after a few Manhattans. We talked it out maturely, set boundaries, and later dated other people. We've discussed the 'what‑if' a few times and decided the friendship matters more.

So go ahead, talk it out, it'll be fine

I think you both should talk before crossing any lines. Things are likely to happen when you're alone at night, so having clarity beforehand will help.
