Need some advice

I was living with my in laws and couldn’t handle it anymore especially being postpartum with twins so I left and went to my parents house. My husband said he’ll work on getting a house but I just feel like he’s so laid back with the whole process just because he knows I’m at my mums but it’s overcrowded at my parents house. Even when I was living with him, I kept insisting he gets a house. He doesn’t want me to work etc otherwise I would. He keeps investing money in his businesses but he would rather achieve his own goals than do something that would work for me. I’ve supported him with all his business plans but feel like if he has the money for investing he should use that as a deposit. Instead his excuse is that his earnings will be more and then he can buy a house. He’s so busy with work anyways not giving me or the kids time and I don’t know how long this is going to run for. I don’t feel comfortable staying at my mums for too long, it’s already been two months. I’m tired I feel like I’m a single mum having to care for my kids. I just feel like I’m getting stringed along by being told he’s going to buy a house. I would also be happy with rental Idc as long as it’s a place for our kids. What do I do in this situation? Yesterday he come to me and said he’s going to need to invest 35k into a business to get a 10% share. He asked me if he should go for it but I had no words to say. Don’t know what I expect from this post but just some opinions. Should I just wait a couple more months 🙃🙃
