Am I overreacting?

So when I was about 5months preggo my husband went out to see a game and he was supposed to bring me dinner bc I hadn't eaten in all day, he stayed out till 4am knowing I was hungry, alone and he had the car. After that he went out with a cousin till 6am I was 6months and when I was almost giving birth he went out again, he acts like is nothing that I was in a high risk pregnancy alone at home. After I Gave birth( C section) the same day the baby was realesed from the hospital he went out till 2 am, then he went with a coworker to accompany him and again stayed out till 4am. Now I found texts that he's offering a "friend" female friend money bc she wants to go to her dads town and calling her gorgeous and he has been texting and calling a side piece he had before we where together, am I overreacting?
