It physically hurts to miss HIM

I moved to UK like 10 days ago for my masters and a better future. Me and my boyfriend have been dating for 4.5 years and he has supported me to get here so much that I probably wouldn’t have been able to come here without him. Our parents know and support us. We are building our careers to help sustain a life together. We talk everyday, stay on video calls. Also absolutely madly love eachother but it physically hurts whenever I miss him and that is like ALL THE TIME. I haven’t cried for anyone which I know seems weird but I always cry thinking what we could have been doing rn if I hadn’t made this decision. Me moving abroad has been a plan since before we started dating and I always made it clear to him that this is not something I’ll budge on and it was MY decision but it still hurts so bad that I don’t know what to do. I love it here. I absolutely love what I am studying. My routine is perfect. Staying away from family is helping better my mental health But it’s just I don’t have HIM…..
