How high are my chances or am i delusional?

Some Info: My heart was broken 4 years ago,which left me devastated. I felt like I didn’t have a heart for all this time. I am M20 and she’s F27.

We are colleagues currently. I am in Italy for work and arrived in September. She arrived like 3 weeks after me. At first we were distant,just co workers who greeted each other and that was it. But after my car tire broke,I told it to her in a casual talk and she offered me help and told me some stuff I can tell the mechanic(she’s Italian and I am not,so she helped me with the language here). I didn’t see her as more then a co worker but in this moment I felt like I need to thank her so I decided to make her cookies. So on the next day I got up at 5 and make her cookies. On this day later I gave her the cookies and she hugged me and was very happy. In this moment I realised I fell in love. My heat was like it was revived in this moment. Since then we started to talk more,laughed together while work and went from just a Ciao for greeting, to a Ciao Caro(my dear) to a ciao Tesoro(my treasure) and to goia(google it). We also give each other air kisses when we leave. And completely randomly she once asked me like 3 weeks ago if I wanna go to McDonald’s to eat with her. I immediately said yes, later we decided when to go. We went to a McDonald’s in a Shopping Center. Before we ate,we went on a little shopping tour bc she needed Christmas gifts. I never enjoyed time so much in my life as in this moment. We made many jokes while shopping and later while eating we had many interesting conversations. After we left we sat a bit in her car,she drove me to mine on the parking space(she parked near the entrance,I didn’t). We hugged each other before I left and then she told me to write her immediately when I arrive at home safely. I did as she asked and also thanked her via a message after my confirmation that I arrived safe and I thanked her for the evening and she told me there will follow many more. I was so happy. I decided to buy her a beautiful watch I saw some days ago as a Christmas present. I gifted it to her on the day I left for home(I work in Italy but for 2 weeks I drove to my home country for Christmas). She was sohappy and also had a little thing for me. She also hugged me and told me to write her at every break I make during my drive so she knows I am safe.

After she opened the present on Christmas she wrote me a long,very lovely message where she called me a „grande amico“ and a „Bella persona“. We also decided to go to eat at a nice restaurant she knows after we return to work after our Christmas vacation. I am so happy. I am a bit scared about the amico part,but I am so in love so I can’t kill my hopes right now. I still hope I have chances. What do y’all think? Do I imagine everything? Am I delusional?
