Girlfriend went back to her hometown. She didn't send me a message during the day. She delivered it at night.

Your girlfriend hasn't been home for over a year. She must have a lot of things to do when she comes home, such as chatting with relatives and friends at home and getting together. It is normal to be tired. She can send you a certificate at night to prove that she still has you in her heart. If you love her, do not doubt her. Trust her. Isn't it tiring to be suspicious when two people are together? Let's wait until she comes back. I hope things are not what you think.
