I am not english speaker so I don't have perfect english.
I 20f and my bf 22m are in kinda good relationship. But there is one thing that's bothering me. But let me give you a context how we met. So I have a friend 20f and she and I are very close friend since highschool and my current bf studies in her college and at first he was her crush (I know it sounds so wrong but just hear me out) but the day he saw me he liked me and he never make any false effort towards my friend and knowing he was my friend's crush I didn't cared about him. And slowly my friend moved on from that guy and they two became best friend and she dated his best friend and she made me date her (btw I did liked him but just never said anything because he was her crush) but she said she has moved on and deeply love the other guy. And she wanted me to date him. So eventually I dated him and I was loving it but his closeness with her bother me.
Let's call him sam and her minni (fake names). So sam and minni are pratically together always. Everyday we meet after college Sam me and minni and her bf. but once we leave they walk around there and I was fine with them walking around at day but they use be together at night mostly they walk around there for hours at night also and sometimes he go to her place to sleep and I told him not to go out at nights and he agreed and stopped going at night and I was happy that he stopped but suddenly he went to her house 2 days earlier and he did not even asked me. And I was shocked and next day when we met he didn't even hugged me and talked for less than 1min and went on his phone and I was standing there looking at him. Then minni and her bf came and we went to cafe and he was not walking with me we was busy on his phone or minni and her bf. I already felt so bad and last night I had told him that I couldn't sleep because I had a back pain but he didn't even asked how I was. And when we reached cafe he didn't even sat with me so I went myself and sat beside him and he was on his phone whole time ignoring me and after some time he moved aside and I felt so bad and humiliated and I called my friend and walk out and I was out for 30min and he didn't came once for checking if I was okay or not. I was so hurt that I could hear my heartbeat so loud and I could feel the pain in my heart (never felt like that before) but he didn't even came to check . He called me but not stood up and walk 5step to see if his girlfriend is okay or not and after that I felt so humiliated and unwanted so I walked inside and took my bag and left without saying anything. And then he was angry, he didn't even texted me I had to text first. and he doesn't think he is wrong here.
Is this worth breaking up?
