My fiance wont let me go

I just started a new side job to help provide for my family on top of my fulltime job.

There is a huge 4 day event out of state next month that I really want to go to because it could really help my business. My upline bought my ticket and all of the girls on my team are so excited to go and meet each other- we all live in across the country from each other. My upline even bought my ticket and a nice house for us to stay in.

My fiance does not want to let me go. No one is bringing their spouse, so I know he just wants to keep an eye on me. He said he's not comfortable with me going out of state with my girlfriends/team for 5 days and that the only way he will be ok with me going, is if he comes too.

I dont want him to come. I just had a baby 6 months ago so a trip with other moms would be so nice and refreshing!!

What should I do?
