I think my husbands cheating on me

I have seizures, no license and no job. The only people I have left to turn to live 5 hours away and moving while 9 months pregnant isn't the best idea... 
My husband hid conversations he had with a gamer girl a while back and he's showing the same signs now. Always on his phone, making things that I do that use to be normal out to be weird or annoying. 
My gut tells me he's cheating. Whether it's sexually or just keeping a convo hidden. 
I tried being more perfect, more sexy taking on more responsiblity even tho I shouldn't at 9 months pregger.
And now he's accusing me of cheating. 
I was furious walked out of our bedroom now he's pushing me away. 
I love him, he has very sweet parts to him that would take to long to write. 
But I would love to feel appreciated and loved the way I did at the beginning of our relationship, the way other girls are probably making him feel now. 
Nothing I do is good enough for him... Sometimes I wish he would leave me so I could date guys who would make me feel okay about myself again.
But I know I would never get physical with anyone else and I want him in our babies life 100% ...
I can't leave physically right now but I'm so confused on if I want to stay. 
He's the type of person who if he thinks I'm cheating will sleep with 10 girls to get back at me. 
Is this what emotional abuse is?... 
I just want him to not make me feel like crap anymore 😞 I want him in my life I'm just sick of giving 100% and it not being enough
