Venting group discussion

I have this ex. Right? We broke up on “good terms” righttt. Well im tryna move on and move forward but i still HAVE to be around him at the least 2 a week. And my friends are his friends. So im tryna be friendly, and nice and complimentary and tryna be friends again, but bro is DELIBERATELY ignoring me and excluding me from my friend group and like totally just kinda making fun of me sometimes? (Laughing at me when i mess up) and like it makes me fill so crappy and unwanted. Anyways yeah thats my vent ‼️
