I miss my ex and I don’t know what to do

I don’t know how to really start these so Ima just go for it. 26 m, I’ve been for a company for almost 2 years and months ago a girl 25, started to work at the company and I liked her instantly. For the first month I tried to get as much information about her before talking to her. It took a lot of time for me to build up the nerve to talk to her, I struggled to even look at her in the eyes without smiling. One day we got to work a 10 hr shift together and we just talked for the 10 hrs. I really liked her but after that I was an asshole to her because I didn’t want to get to close to her. She stopped talking to me for a while and after months she started to talk to me again. I was able to get her to go on a couple coffee dates and get to know her and we became something amazing, she was able to get me to see a future and having kids. Everything was perfect till work started to drown the both of us and we didn’t get to see each other often. She was moved to the night shift and we kept seeing less and less of each other. She would get off around 3 or 4 in the morning and I had to be up and ready at 6 am. In April I decided to quit my job because of the work and pay ratio and went to another job 2 weeks after quitting. After I quit she broke up with me, I tried to beg her to make things work but she said things weren’t the same. It’s been almost a month since we broke up and I can’t stop thinking about her, I really want to go and talk to her and hope she still wants me and we can figure something out but I feel a lot of hesitation because of hoping she might come to me which might sound stupid but I guess I just want to feel wanted by her. I don’t know what to do
