I'm 23M and as the title says, theres a really sweet and pretty girl (23F) who moved into my friends flat in February. At the time, my friend had only told me that they found someone to move into the flat and nothing more. I didnt know what they looked like or their name etc.

Then a few weeks later, there was a house party at my friends flat. I met a very pretty girl who I really got along well with. We had one of the best chats I've probably had in a long long while and after she left that night to go to a club with some of her friends, I was thinking about her for the rest of the night. The next morning a few of my friends separately bring up that they saw us talking for a large portion of the night and were actually praising how invested she seemed to be in the convo (I didnt remember too much from the end of the night lol). In fact even the my friend who lives in the flat said it aswell, but also told me that she was in fact his new flatmate and she had a boyfriend.

After hearing that, and being the gentleman that I am, I ditched all thoughts about pursuing it any further.

A few days later, the friend that lives with her messages me saying that she was asking about me and how he knew me and said i she thought i was very attractive and cool to talk to.

The day after that I go to said flat to pick up something I left there over the weekend. One of the other flatmates is the only one home and says to me she was talking about me to him and also told him she thought i was interesting and attractive. Thats two separate stories from two separate people she lives with. ngl this was hard to ignore.

over the next few months, I see her more often as we go to my friends flat on a semi weekly basis. we play drinking games, I notice she pokes fun at me. picking me out for challenges and picking on me to drink and all that.

since at this point we were decently good friends (not good enough to like hang out without my friend who lives with her, but still pretty good), and I thought she was hot so I decided to add her on instagram. No follow back. I didnt think twice of it.

by this point I had met her bf and he was actually such a sick guy. he was 27M and seemed to be doing good for himself. a hard guy to dislike. we got along quite well.

some more time goes by and more house parties and flat drinks. One time when going out into town after a flat drinks she wants me to come, but i dont as i didnt bring my ID because I wasnt planning on going to any clubs that night. she seemed a little disappointed but maybe thats just me making it up in my head. Anyway, before leaving she gives me a goodbye hug and then something that really surprised me. she grabbed my face and planted a kiss on my cheek. at this point I was super confused but again was aware of the boyfriend situation so tried my best not to think too much of it.

Another night when I again didn't take my ID and couldnt go into town after another flat drinks (I know, i should start anticipating these things by now), she offered her bed to for me to sleep in for the night because I live quite far away and usually just crash on my friends couch. her bf was there and he was on board with this idea. she wouldnt be coming back she would just go back to his place. My thinking is, I wouldnt let anyone but a few of my mates sleep in my bed, my bed is my sacred place. So she must be comfortable enough with me to let me sleep there? but again i cant assume she thinks as I do so maybe nothing to think of, but though I should mention.

about two months ago, I did a massive instagram clearout and unfollowed everyone who isnt a football player, a chef or someone I knew quite well irl. she didnt make the cut as I only saw her maybe 1-3 times a month.

2 weeks ago, I heard from my friend that she broke up with her bf recently, because he was older than her and was at a different stage of life. A couple of days ago i was heavily thinking on this and decided I'd follow her back on instagram. This time i get a follow back...

in december, everyone in my friends flat is moving out as the house is being sold. were having one last event there as a send off.

how do I go about this? should I leave it be and give her some time? My other friend whos far far more experienced with women thinks I should try talk to her at the sendoff event, and if i get too scared to hit her up on instagram later. But im not sure about this at all.
