I can’t handle it anymore

So my partner is driving me insane. I am a stay at home mom. I do everything. It’s a lot of pressure. The guy doesn’t do anything around the house. Guess he thinks it’s a woman’s job? Idk. I don’t get any of his money either. He will pay my bills but that’s about. Now the part that really angers me. He has a job. Which cool good for him. Now he doesn’t know when he’s working, no days off, no stability at all for me to function my own job right now. Or for the past damn near 2 years. Now he comes home, doesn’t really play with our shared child because he knows he won’t play with him. He barely gives his dad the time of day because they don’t have a good bond together. So he’s a mommas boy. I show him love, I give him the time of day.

Now also my son has to be tested for autism and I truly believe he has some signs of it. No I don’t want him to have it but as his mother I been keeping an eye on him. Maybe he’s just your typical toddler but better to be safe than sorry and him not knowing who he really is his entire life. I also don’t have any childhood education, he’s my first child. And probably my only. So I don’t know everything. I’m very worried about his dad’s reaction. I asked him how he would feel if we found out he is autistic. He said he would be sad but can accept it. I just don’t want him to blame me or something because I asked the pediatrician and she told me if he has it, it’s not something I caused in pregnancy or in his life. It’s nothing I did. I’m really thinking it’s almost my time to get out of here. Like I’ve tried so much. I expressed how important spending time together is. He don’t believe me or something. He was brought up differently than me. I was taught discipline and there’s consequences to my actions. I have 2 brothers, growing up this guy didn’t have siblings at all. He was brought up with people telling him everything will be ok, he’s always right. He didn’t get in trouble for lying or anything how I did. I just don’t understand how this guy is still the same after years of me expressing and literally telling him my love language is quality time. His is acts of service. It’s just not working out for us. I wanted a partner to spend life with, not someone to spend it apart. What the hell.
