Do you guys ask to be his gf?

Hello, i am dating a German M 43 single father and i am Mexican F 36 single mom as well. We both live in Canada and we know each other for years from work, but we never tried before. Came back to work last year, and we crossed paths and we liked each other again. So, we started to talk more in Nov, we had 3 dates, went to Mexico for 2 months and we were long distance relationship. Now, i am back and we’ve seen each other a lot every weekend and at work if we are lucky to run into each other. What surprised me is he pays the bill every time we go to dinner or other stuff he buys for both, sweet, passionate and we got closer, like too close already. So from long distance to now, 4 months. However, he didnt ask me to be his gf, wondering if German men asks to be his gf or do i have to ask him like what are we ? We always say each other amor=love. I dont want to pressure him by hey what are we? Cuz we arent getting younger anymore and we have kids. What do you think? Thanks
