Is my boyfriend wrong for not inviting me to his family birthday BBQ?

So first of all I feel when you have a relationship and you have issues in your relationship you don't go running an tell your family everything all the time and because that only makes them lose respect for your relationship your other half and go against your other half and whether you choose to stay with your other half or not is soley up to you but if his family doesn't like you anymore and his family goes and throws him a bday barbq and you ain't invited to it and he's just ready to go wout u is that wrong?
