Swore in today

My boyfriend swore into the Air Force today. This has been a year long process so I’ve had time to accept the fact that it was most likely going to happen (he had a medical conditional that prevented him from getting in this time last year) but I feel completely taken back and in shock knowing that it has actually happened. I’m so so happy for him as this is the best thing for his future and something he’s always wanted, but I’m scared of what it will mean for our relationship. It’s been a year since we started dating, before that we were friends/coworkers for a couple of years. He helped me out of a toxic relationship and has made me a better person. I know our feelings for each other are mutual and I’m willing to go through the hardship that couples endure when one is in the military but I know there’s a possibility of it not working out, especially because I have children so the option of me living with him when the time comes would be hard for me to do. I don’t have anyone to talk to about this so I just needed someone to vent.
