Boyfriends parents helppppp

Sammy

So I’ve been with my boyfriend for over a year now and we’re both 18 , just graduated but his parents for some reason don’t want me around to celebrate anything with him. I wasn’t invited to his 18th birthday dinner and they rarely let him hang out with me.They make excuses or ignore him when he asks and I don’t know what to do or how to talk about it because when I do it leads to nothing 🥺 they recently talked to him and said that we can’t do everything together and that we need to be independent in our own ways and also said that I need to drive myself around and buy my own things even though HE is the one that chooses to pick me up and take me shopping, I just feel like they don’t like me ): can someone help and give advice ?
