How to feel?

My husband and I never go on any dates or trips. Most times we are just home with the kids or I am working. I don’t have many friends, definitely none to take any trips with. My husband has a family member that wants him to leave and go to Detroit and Florida apparently all this weekend out of nowhere. On my two days off work. It’s not that I don’t want him to go exactly, I’m just salty mostly because we never go anywhere and I don’t go on any trips or outings even in the state. I don’t have anyone offering to take me on free trips or have fun. We just don’t have money or babysitters for 4 to travel, so as a family l, we don’t do much at all. As a couple, we don’t do anything either to be honest not even at home except chill. Again, this trip is free, but just for him. Not the family. We’ve been married for awhile. I’m not trying to be a brat. In ways I want to say just go but being honest I just feel some kind of way. If I told him to go, it wouldn’t be an all in yes. 🤷🏽‍♀️ if I say I don’t agree with him going, it’ll be a lot of attitude @, but he wouldn’t go. I need some input.

UPDATE: I am allowed to have feelings. Just like you all and I don’t judge for them. You don’t have to like it but at least I can be honest with my husband instead of lying about it. Just telling him I’m happy for him to go, and I’m not. Some of the comments are saying “I’d want to go” or “you’re bored” and it’s annoying. Learn to read. I also said it’s not that I didn’t want him to go. All I do is work and take care of my kids. I’m pregnant 🙄. We don’t have a car. And 4 KIDS. We “suggest” things to do all the time together and they don’t happen. So yeah again I’m allowed to feel. For the info, he is going. And my feelings haven’t changed. But yes I gave my half approval. There are a lot of honest and supportive comments (thank you) but just as many rude unnecessary ones. (No thank you) I don’t have a lot of friends i can talk to so I though I’d come here, from time to time,for honest opinions from people I don’t know, yes but SUPPORTIVE ones. ✌️
