Venting

I'm sure people are over it , but I dont have anyone to talk to so I just write down what I'm thinking or feeling or going through here and it makes me feel so relieved in a way. Today, our kids grandma wanted to spend the day with them (2 and 10 months) I thought it was great and would give us some alone time together and we could have a good day, but when we got home he stayed outside the whole time messing around in his garage with his bikes, I saw him coming and going and texted him and he ignored it. Then they brought the kids back but they hadnt eaten dinner and I didn't make anything or get anything out because I thought they were eating there because thats what usually happens when they spend the day so I figured we could order a pizza or grab something quick because we havent gone grocery shopping yet. I called and he ignored it right away, I asked where he was and he told me down the street at his friends house. Ok I asked him to come back soon so we could get dinner and he left my message on seen, I called a couple times and he sent it to voicemail, texted him and nothing so I threw together a meal for the kids. Quick sandwiches but my 2 year old is over them so he didnt eat much of it. He's still gone and hasnt said anything or let me know anything. Im just so frustrated and tired of the disrespect. I have NO problem with him hanging out with friends but he told me nothing and made it seem like he'd come in for dinner. On top of it all I'm pregnant and so emotional and just want to cry. I wanted to spend time with him and he blew me off all day for some friends.
