Bf (M26) is starting his new full time job and i’m (F26) feeling lonely and anxious any advices?

hi all, my boyfriend(M26) is finally starting his new full time job after graduation and we used to meet pretty often all the time and go gym together especially for the last few months. however, he is starting his job next week and i can’t help but feel sad, lonely and anxious. im afraid that things would change and we’ll meet up lesser which might affect our relationship OR the possibility of meeting someone new at work as i did have a bad experience with guys i’ve previously dated saying that they need a ‘mental break’ and had ‘no headspace’ because of their busy work schedules which ended up ghosting me and that affected me pretty badly.

he did also mention that he is driven and wants to focus on work to do well and im worried that my emotions will tire him out mentally and physically in the long run if i keep wanting to meet up. i will be starting my masters in august so our schedules will be pretty different as i have evening classes (he does 9-6). we did plan that we would allocate one of the weekdays to meet up for dinner after work/school and sleepovers at his place on alternate weekends. i know i should prioritise and focus on myself to do activities which keeps me busy but i cant help but have these thoughts in my head because of the sudden change. (i think i have anxious attachment….)

any girlies out there who have experienced this, any advices please? thank you.
