Found out I’m pregnant before holiday… do I tel him?

Okay so I currently have two under two. I found out today I’m pregnant with another … we have not planned or expected this what so ever . Our relationship is not in the best place right now and we 100% would not keep it.

My partner and I are supposed to go on our first long weekend away tomorrow night together without the kids.

Do I tell my partner before , during or after the trip?

I feel like we definitely need this reset to bring back intimacy, romance , fun and love back into the relationship and I don’t want to ruin it with this news.

Yes I was on contraception.
