Boys trip while pregnant

Any thoughts? My husband mentioned to me today that he wants to plan a boys trip for a weekend with some of his friends but I have no trust in him at all due to some previous things he has done. Plus I am pregnant almost in my third trimester.. not sure how to handle this. We have been together for 8 years and already have a 1 year old together and two months ago he did a wrong and that’s why I can’t him anymore ..
