Am I crazy? I’m so upset my bf and his best friend recently reconnected again. They both started dating at the same time so I was with his friend and his gf ALOT these last 9 months

So anyways he calls him today and when he asked if my bf told his mom about me(he did and his friends gf knows because we still talked) he lied and said no at first then lied again and said well yeah but I told but then told her we broke up after the fact(they both can’t date because of their religion)

Then when his friend asked him well are you going to stay with her he literally didn’t even say yes.... said something along the lines of were just doing what we did before. Like I’m not worth a yes I’m staying with her?????? We’re 20 and 21 I don’t understand why he would even say that(apparently because he didn’t want to open up to him)

Am I wrong to be getting emotional with him? I’m already a secret when it comes to him and now he can’t even with his old best friend?😞 I feel so hurt and lost am I overreacting?
