Search Results: leaving him

I was out with a group of friends, during the night my friend met up with her cousin and her friends, there was a guy in the group who was drop down my dream guy during the night I saw him looking over at our table and making eye contact with me and smiling. I presumed he was just being friendly.

Later in the night as we were all leaving his friend (who is also a girl) shouted across to say I was gorgeous, and she loved my hair, he was standing with her smiling and held eye contact. It could have been me but I felt he was interested, but I'm not sure if he is just a sweet and friendly guy. As we were leaving he hung back and walked across with me smiling while my friends joked about me being gorgeous (he was laughing and smiling the entire time). We didn't say much together when we walked alongside each other. I walked in behind him and he held the door for me, a guy came into my face to chat me up and he was holding the door for me smiling again and waited until I went in and brushed off the other guy and ran inside. As we went into the bar he stayed standing near me by the wall while his friends went to the bar, again another guy came up and he smiled again.

Throughout the night I would keep catching his eye but he never once tried to make a move or talk to me. My friends thought his friend was trying to give him a pep talk but he never did come up to me. What do ye think?

Me and my cousin are of same age and ever since we were kids, we would always be together in everything. play, fight, eat, sleep everything. we knew eachother's secrets and always had eachothers back. We would call eachother everyday to update what's happening and how our day went. suddenly from last 10-ish months he began avoiding me. no calls, no texts, no replies... but he would put on insta stories and call my father, but not to me. This really hurt me knowing that we both are legit like BFF'S that our entire relatives loved. So i asked him in a huge para about how horrible I'm feeling. all he said was he has a girlfriend and the only condition she kept for him was, him not talking with me or talk about me (she knew about me cuz he told her about me). I really don't want to keep my ego infront of me and kick him out of my life but also don't wanna loose my self-respect. I really love him (ofc not in anyother way) and ik he too. But do you think he did the right thing? And would you do the same if you were in his shoes?
Also let me know, what should I do?
