Newly single at 37

So it's been a month since I asked my husband to leave. It seems he has been punishing me for calling his family bad names in anger. There are very valid reasons for this, so please trust that ladies. I have been nothing but kind and giving to his family, but on occasions, I have blown up in anger, and said some things I regret, due to certain things started by his family. I have never felt like part of his family. I don't have any children, so to come into a family where he has a 19 year old and a 17 year old has been the most difficult of things I've ever done. His daughter, whenever she gets any alone time with me, starts telling me how terribly her dad (who I'm now married to) treated her mum. Even told me that one time he came home to her mum sleeping, and put his hand on her pillow when he went to sleep, and his fingers stank of fish! Her mum went thru his phone, and he'd been out fucking another woman   This is just one in MANY horrific stories she's told me. 

I have put this man first for three years. Made sure his dinner is ready for when he gets home, had his offspring over every Wednesday, tried desperately for them to accept me. I have paid off 8k of his debts, all because I want my husband to be able to take me out to dinner from time to time. 

So for the past two months he's been cold, snappy and basically angry all the time. He spent 8 days and nights in the spare room, going straight up there from work and staying there. I had a dog attack me so I had to go to hospital one of those days, turned out it was very serious injury and they wanted me to stay in but I convinced them otherwise. They had to reopen the wound and I passed out...when I text him to tell him where I was, he responded with "can u tell me how much I will be getting paid next week". (He works in my company) my heart shattered right there. So I asked him to leave.  He's currently at his mum & dads house and since he's gone he's told me I drove a wedge between him and his family, that now he has seen who I am, he doesn't want a baby with me (we have been trying for months now). 

So here I am alone and wondering if it will ever happen for me again. I am too old to have a kid I guess. I mean if I meet someone tomorrow, I'd have to get to know him for a few years first. My heart is broken. Could you give me your thoughts and any advice please. ❤️
