My boyfriend of over a year and I are going to an out of country destination for a week in March. I love him a lot but he can be juvenile and I find myself feeling at times likes a mother and child dynamic.

His passport has been expired since May 2018, and I have brought it up several times to get it renewed. We have even had a tiff or two over it. In November, we booked and paid for this trip. It cost about 1000$ each. 

The deadline of him needing to have his passport sent off so he can get it back in time is approaching quickly. I guess I'm asking preemptively to this so I know if I'd be an asshole if I followed through with what I am currently intending on doing : I'm not going to say shit and let him deal with the consequences if he doesn't get it together on time. I'll have a lovely vacation on my own. 

Be honest. Would that make me an asshole to knowingly let him miss out on our trip?
