Okay, so here is the situation. My husband and I have been with our gf for three months. I'm still not 100% sure I am comfortable with them having sex without me, however, I said it was okay. So then he wants to go on a overnight trip with her. I said I want to go on a overnight trip with her before he does...
So you and your gf went on your overnight trip.
... he was supposed to go on a trip by himself on his bike. He was gonna go visit some family, but it was gonna be a nice long motorcycle ride for him. Well, we ended up selling the motorcycle for personal reasons. So last night he was talking to me about still taking that trip. but with just her. I said no. Why can't me and the kids go too? He asked, "You feel left out?" DAMN RIGHT I feel left out. It's the middle of the summer, there is no reason why me and the kids can't go too.
Is he taking his gf to meet his family? Or your family? Or does he just want to go to that area and not take her to meet the family? (I don't know if you're out as poly to this part of the family.)
And now somehow this weekend trip has turned into five days? That is a hella long trip for your husband to take with the (still new) gf. I can see why you'd be envious/jealous, especially since you'll be home alone with your (and his) kids. When is the last time you and your husband had a five-day trip without the kids?
Can you negotiate it back down to three days? That's already generous with Daddy's time, imo. Also, while they are gone, you could arrange a babysitter so you can get some me-time, or time out with some friends. Otherwise you might feel taken advantage of.
So am I wrong to say that I don't want them to go on a weekend trip alone? I just feel like, why can't we all go? Why do I have to be left out and left stuck at home with the kids?
Yeah, I kind of agree with you here! Not that you need to go with them, but that 3-5 days is a long time to leave you home alone with the kids, as you're still getting used to being in a triad.
