Trying so hard not to text him

It’s only been a few days since I kicked him out but I find myself wanting to text him. Not because I miss him but more of why he chose to do the things he did that destroyed our relationship. I’m also pregnant and very emotional. 10 years is a long time to let go of even though a lot of the years were filled with arguments. I’m just such a vocal person and I like to talk everything out. I’m not able to talk to my friends or family and not even him so I feel so alone. I don’t want him to come back but I’m just so sad because it’s his fault that we aren’t together. I’m never good at not calling and texting even when I’m the one that ended it. Some guys can be so stubborn and not seeing him even attempt to call or text bothers me.
