I feel so worthless..

I'm currently in a committed relationship but he called for a sudden break. I never knew that he was experiencing such heavy burdens while having me around and most of them aren't even about us, it stems from my family.

I am so ashamed to even say this but they're constantly on my back for the littlest things and it affected my boyfriend who got dragged into the mess. My mom and sister never listen to when I tell them to stop or not do something because it makes my boyfriend uncomfortable. They have zero respect for boundaries and I've grown up so messed up because of the things that they've inflicted on to me.

I've always told my boyfriend not to do this or that when it involves them and to speak up if ever they make him uncomfortable. He's pretty well off and didn't mind spending but it gets to the point where his kindness is being abused. One of the mountain of things is him having a car. Whenever he comes to our place, intending to rest or just chill, my mom insists on going places because of the car. She thinks that she is entitled to demanding things when in reality, it makes both of us extremely uncomfortable.

I try to tell him not to feel pressured by them or place unrealistic expectations on himself because of them but I think it's hard on his end because they're such prominent figures in my life. He feels obligated to do things despite my endless reminders of not doing it or trying to stop him from going overboard on spending.

I'm so confused and embarrassed because he has spent a good amount of money on me and I have no way of returning it if we break up because I'm still looking for a job. Though, he never wanted me to return the things that he gifted me because he says it's meant for me but I feel so guilty and hurt.

I wanted to talk about it and we did, kinda, he just dumped it all onto me and asked for a break. Now, I don't know what to do. He is my first in literally everything and I wanted to build a life with him so I can support him emotionally and financially but I think my family is getting in the way of literally everything I've done in my life. I hate this so SO much.
