My hurt feeling

Recently my ex comeback to me and asked me to be his girlfriend again.i thought he was joking around but he swear if he serous about it.then i told him if he wants me comeback,he must prove it if he sincere about it.he proves it if he really serious.
But yesterday his bestfriend forces him to courts a girl.actually all of our friends have not idea about we getting back together.my ex overwhelmed when his bestfriend set a date with that girl.okay honestly that girl is better than me,his beatfriend say it in front of my face if this girl better than me (in jokes way,but it's still hurt a lot).so the girl who happened has a crush on my ex,and his bestfriend owed her so much.and what's it's really hurt,i am clearly a good friend with him but no one mind about my feeling.
my ex confuse cause his bestfriend clearly not approve we are getting back together.just cause i dump him (not in mean way) he thought i am a cruel one.honestly it's really hurt me,but i don't want to speak it loud cause it will become more complicated.
so my ex drags me out,so we can talk alone.he confessed if he just wants me and no one else.he blabbers about his plan for the weekend,he planned to spend it with me,etc.since everyone not mind about my hurt feeling,i thought i can't be selfish.i tell my ex to move to other girl,cause that girl has a lot more thing can make him more happy.and everyone won't approve if we together again.i tell him it's okay if he want comeback with me but it will more great if he thinks other feeling.and my ex choose to leave me,it's for the best right?
