Boyfriend is slowly Pushing me away

I’m so tired, overwhelmed and exhausted. I have invested so much into my relationship. We’ve known each other for 7 years now but committed for 2 years.

But I’m actually getting to the point where I’m questioning whether or not this relationship is for me.

My boyfriend is trying to build his business but is expecting me to wear all the hats while his family does minimal work and reaps the benefits (money) while I’m investing into so many areas that they are not. He expects me to do all of that on top of holding his family’s hand coaching them through their role as I’m still learning mine.

On top of the business frustrations, I live in the family home and help him pay the bills when his siblings live here as well and are unemployed. I come home from working a 14 hour day and the kitchen is dirty with dishes piled up, and the trash overflowing. And lights on in every room.

Every time I converse with him about something pertaining to his family he takes their side and enables their behavior. He also will give me short answers and barely converse with me when this is mentioned.

I’m extremely exhausted and love him to death but idk how much more I can take.

Can anyone else relate and provide suggestions other than the easy route of leaving? Leaving is the last option but if there’s nothing else to do that’s what is going to have to take place.
