I've got a gf, but I sit and watch anime with a girl I don't know who's also in my house

So here's the thing, my friend cheated on his gf and she moved out. She lived with him in the apartment he now lives in. I moved in after she moved out and I don't know how to explain this properly, but we've lived in the same neighborhood since forever and I've known her since forever, she's like a childhood friend or something, it's complicated. <br><br>Anyway, she took all her stuff from the apartment and moved to her parents place, and my friend was left with a half empty apartment. I agreed to move in and when I told my gf, she asked why I was moving in with him when I'm already living with him, in our apartment, so I told her the truth, he was in a fight with his gf so I could move in, because she moved out. <br><br>My gf got angry because she felt like I was lying, but then she calmed down and said it's fine, and that she'd help me move my stuff to the new apartment. I agreed, and we moved all my stuff, and on moving day my friend's gf came to pick up the last of her things, and she saw my gf moving my stuff in, so she started crying and getting all mad, and saying stuff like "I knew you wanted me to move out" and "so you're finally going to live with the girl you've been in love with since childhood?" and stuff like that, even though we never dated or, idk, went out, or even kissed, or anything. We were just friends and stuff. <br><br>So my friend's crying too and saying he's sorry, and my gf was looking at me with a weird face, like "you know her?", so I told her the truth, that she's a childhood friend, and lived in the apartment I just moved into, and she got pissed and said she was going home, so I tried to calm her down, but she said she wasn't going to waste her time in an apartment where I'd rather live with my friend and his ex gf whom I'm in love with. <br><br>So she took the rest of my stuff and left, and my friend was still getting yelled at by his ex gf, who kept telling him "I knew you wanted me to move out, so you could live with your gf who's moving in" and stuff, then she started crying more and saying "I never meant to hurt you" and stuff, so my friend said "I never wanted to live with you, I'm glad you moved out", and that made it even worse.<br><br>Now I'm living alone with my friend, even though I never agreed to, and my gf is ignoring me because she thinks I want to live with my friend's ex gf, and I don't know how to explain it, because even I think it's too weird, but my friend's ex gf doesn't live here, she just comes over and sits next to me on the couch to watch anime or something, and I don't know what to do, and I felt like asking here, maybe somebody else in a similar situation can help me figure it out.<br><br>&#x200B;<br><br>Edit: OMG THANK YOUUUUUUU FOR ALL THE HELP THANK YOUUUUUUUUU, I went to my gf and explained it all, I even showed her this post, and she calmed down and said she's sorry lol, but then my friend was still crying and stuff, so we went out drinking, together, and my gf even joined us, and we got super drunk lol<br><br>I feel bad for my friend, but I'm glad my problem got resolved, and I appreciate all the help you guys gave me, it meant a lot lol, but I'm still gonna tell you how my friend's situation turned out.<br><br>So my friend, after he got sober, told us that the reason he wanted to break up was because she got pregnant with another dude's baby, and he was going to raise it as his, but then she miscarried, but he still wanted to be with her, so he pretended like nothing happened, but the day I moved in, she came to tell him that she got pregnant again, but with the same dude's baby, and he got angry, and that's when she started yelling and crying and stuff, and I'm just sitting there watching my friend cry lol<br><br>So my gf goes "you should just go talk to her man" and stuff, and we're all like "yeah dude go talk to her, don't leave her" because my friend's a good dude, and we all felt bad for him lol, and at this point we were all super drunk, so my friend goes "ok" and takes out his phone and texts her, then goes "ok I'm gonna go, wish me luck" lol, and we all go "GOODLUCKK!!!" lol<br><br>So he goes to her place, and we're waiting for him to come back and tell us what happened, and we're all excited and stuff, then he comes back, and we're all like "what happened?!" and stuff, and he goes "I'm a dad"<br><br>We're all like "what?!" again, and he's like "I'm a dad, it's my baby" and stuff, and we're all "WHATTTT?!" lol, and he goes "I'm a dad, because the baby is mine, I just got the paternity test results, and it says the baby is mine, and it's a boy, so I'm a dad" and stuff<br><br>We were all shocked, and stuff, and I was like "wowwwww, this is insane lol" and my gf was like "omgggg, congrats dudeee" and stuff, and my friend was all smiles and stuff, and he was like "I'm so happy, I'm finally a dad, and I get to be with my girlfriend" and stuff<br><br>So yeah, my friend is happy now lol, and he's gonna be a dad lol, it's all good lol, thanks for reading, and I hope you enjoyed the story lol, and special thanks to the guy who wrote the poem lol, made me cry lol
