Would you trust or not? Why can’t men understand!

So this is my question about men. You absolutely, don’t trust him and he decided to signed up for a training for work, in which he never considered your opinion. You both have a conversation about how you feel about his trip. He said, I’m just going for work. Which, you understand. Of course, his coworkers are way younger than him, and think differently, act un appropriate as well. although, they are in a relationship as well. He then says, I am a leader not a follower. You are almost close to having your baby, you been going through a lot in your pregnancy because of him and he’s lies. So being a couple of hours away from home and from you made you feel lonely. He never been out very late at night with you not even when you weren’t pregnant but this time he was and didn’t considered the way you were feeling and thinking, and knowing you don’t trust him he still went out and stayed up late. I feel that since you have no trust he should considered that and he should gain your trust by acting differently. I guess, expectations from him was not to be out too late since he wasn’t there to party and to think of how it made his women feel knowing she is pregnant and very emotional because he has done things that has made her insecure and doesn’t trust him. How would you take this?
