How do you know you miss the person or the benefits/intimacy it brought?

I dated a girl for around a month and it was really nice. Went out a lot, cuddled etc I just felt like I somehow connected to her in a deeper lvl its been really long since I felt that way. Now it ended because of work and I haven't really seen her since a month and I must say I kinda started to think about her quite often.

I dont want to tell her this, as she was the one who doesn't have time bec of her new job and ended things and I dont want to chase (I dont care if it was an excuse or the truth, a no is a no in the end).

I just want to get it clear in my head. I miss having someone to connect to, hold hands etc stuff couples do but I don't know if im just thinking of her as she's the closest one to be that person in the recent years or if I am just touch/love depraved basically.

Or if I miss her as a person but I don't know I know her for longer but always saw her as a friend until recently. We never hang out much tho so I barely knew her and only got closer on a trip toghether after which we started dating.
