I, 23F, live with my close friends (23F) of 6 years in the same apartment and work in the same company as well. Around 2 years back she referred me to the company and invited me to stay over at her 2BHK apartment. After moving to the city, I met my current partner, 26M, let's call him A and we have been seeing each other ever since without any commitment. A while ago I started getting attached to him and told him about my feelings. He was respectful and understanding but told me that he is not thinking about pursuing a serious relationship. I didn't mind because we are really close and always support each other through thick and thin. My flatmate who met her boyfriend a year ago is committed to him and they are going to get married. Sometimes when her man and my partner are at our place we all hang out, use leaves and chill out. I always looked forward to it up until recently where I started noticing my friend and A laughing a little too hard at each other's jokes and staring at each other. Now normally I wouldn't mind two of the closest people in my life getting comfortable with each other because I'm close to her boyfriend as well. 2 weeks back it was just me her and A and normally when she is with her boyfriend I never intrude. She grew up in a joint family and has a hard time understanding the importance of giving space but she doesn't understand that and I wanted to be left alone and ended up asking her to leave over text, obviously. It's not just the space but the way they laugh at each other's jokes all the time and he asks where she is makes me uncomfortable. AITAH?
