Can anyone tell me what to hope/do?

I need to get this off my chest.

Sorry for this long post,I need to tell it to someone. Some maybe important information: I (M20)moved to Italy for work about 2.5 months ago. She(later you get more info,F26) is working at the place I work for about a month now I would estimate,maybe 5 weeks,can’t tell exactly. I can speak Italian about B1+😂 Also an maybe useful info is that I got my heart broken 4 years ago and since then I felt like my heart was ripped out and everyday there was just a stone

So,as I told you in the intro,I moved to Italy for work and I have a coworker with which at first when she arrived didn’t have so much contact with her but in the last let’s estimate 2 weeks that changed a bit.my Italian started to improve a bit,I got to do more at work, and eventually we started to talk a bit more,not only greeting eachother with a Ciao. But last week,it changed a bit for me. I had a problem with my car,one wheel broke and I needed to go to the mechanic. During work on Monday she asked me how’s my weekend been(on Saturday my wheel broke) and I told her what happened and that I wanted to go the mechanic today(on Monday). She offered to help me instantly and come with me to absolutely have no language barrier. we agreed that she just would follow my car with hers but sadly we lost each other on the way and I didn’t have her number. So we actually both wrote to your boss to send the phone number of eachother and she was faster and called me and then we figured out that she lost my car at a roundabout and so we decided we try again on the next day. I got up the next day at 5 am to make fresh baked cookies for her as a gift. During our talk on this day and also our call after we lost eachother let me feel something for the first time in 4 years,at the place where my heart had been. On the day I made the cookies(Tuesday) she sadly told me she don’t have time today and so I went alone to the mechanic. But when we both went to the parking space I gave her the cookies and she hugged me(this hug was the final straw that let my heart come to life again) and was so happy. Later I wrote her that everything went fine at the mechanic to which she replied that she’s super happy for me and how thankful she is for the cookies and how good they were. I wrote her that that makes me happy and she replied with 🥰😍 and reacted to my message with a ❤️ And since this day(the rest of the week) she constantly says „Ciao Bello“ when she greets me which means like Goodby/Hello(depending when she says it,at departure or arrival) you beautiful one(doesn’t make much sense in English). Yesterday she did this when she went home but also send a kiss with her hand to mr(I hope you know which gesture I mean) and I automatically(like I didn’t think,I just did it) sent one back. Since then I am all over the place with my feelings but what really makes me loose my mind is that in the same day I followed her insta which she accepted and followed back. I sadly saw there that she had a friend but the last post was at the beginning of 2024 so this is currently the only thing that keeps me away from losing everything single feeling that I finally found again. I am finally after 4 years not sad when I wake up,I finally feel something where my heart is again. I really have hope.I feel alive again,I am happy,I think about her randomly, I smile randomly throughout the day. I am just happy again. Am I going crazy? A part of me don’t wanna suffer again for years but I am just to deep in love to let my logic win here. I wanna try having more contact with here now. That’s my goal. Any ideas/tipps/siggestions?
