he never wants to do anything w me?

my husband told me he wants to buy a lot of houses and an apartment to rent them all out. he said hes also going to hire ppl to manage those properties, because he wont have time to do it since hes still going to be working at his current job. since im just a sahm, and our kids are already growing up, i told him ill manage them. he laughed and said i wouldnt be able to do it. i said i can, he then said he prefers to hire ppl to do it. he said itll be a lot of work. i feel like he never wants me to be a part of his shit, and its like hes embarassed to be w me or wants to be seen as a single man. he never wants to do things w me, never invite me to his job events/parties, he just wants me home like a maid. he doesnt like shopping w me either! what do u think and what should i do?
