Should I ask my ex for a date?

My ex boyfriend and I were together for 51/2 months. But we’ve dated once before a couple of years ago and have been on an off and on relationship in between those. It’s important to say that the reason why I wanna see him at least once this year is because:

1. I’m leaving to another country. (He doesn’t know that btw)

2. I haven’t seen him since COVID.

3. We always made plans but never had time until now that the holidays are coming.

4. We miss each other so much.

We broke up because he was starting his senior year and knew he wouldn’t have the time for me and I didn’t want us to have a long distance relationship.

I want us to go on a date before I leave next year on January, because I know I won’t see him again unless destiny brings us together. I want us to have some closure, since our on and off relationship has been going on for a while.

We would be very happy if we could have a moment for ourselves, where we can be each other and have a nice, romantic time.

Since COVID, we’ve known each other so much better than before. I know I love him and that he loves me even though we haven’t said it since our first breakup.

My fantasy is for him to spend New Years with me but I know that’s barely posible, so I’m going to stick with my realistic self. I want us to go to a movie, hold hands, eat popcorn, kiss, and enjoy while we can.

I know he still likes me, and he wants that but hasn’t had the time, as do I. I know it’s silly, but I miss him so darn much but I’m so scared of getting rejected and miss my opportunity of seeing him ONCE before I leave and a new year starts. I haven’t seen him in person in a long, long time. So, what should I do? Im scared.
