So I have someone from work I just started hanging out with. Were both girls and Bi. Shes engaged and I'm in a relationship.

Well we live been making plans to hangout because she just had a bday..yesterday she kinda invited herself to stay the night after work, was a miscommunication on when we'd hangout. Her bf left work early so she had no way home without him driving 40 min to pick her up, so I just said she can stay the night.

....It being last min we stopped at Walmart and got her PJs, she also got me candy and a 2 dollar stuffed animal for Valentine's day. I didn't think anything of it so I grabbed one for her in return. (I thought it was just an innocent friend thing..I still sleep with stuffed animals so I thought she'd do the same) ...Later it was just us at the apartment and she came out the shower naked and got dressed in the living room because her stuff was there. I had no idea what she was doing or what to do so I just left the living room.

...I told my bf I saw her boobs and he's super upset with me, I didn't know she was gonna do that. I thought it was just her being comfortable with her body. Idk.

...SO now I have to have a conversation with her about it and I have no idea how to do it without losing a friend. Shes my only friend but I don't want him upset with me.
