I need advice for dating!!

So first Hello. A woman at my gym and I started seeing each other but it was super random between sets and it was for 3 days and on the 4th day as we were passing each other she looked at me and smiled and said “good morning” and then ” good morning” she started standing next to me and even when I started stretching after the workout she started stretching next to me and started a small conversation, I complimented her on her beautiful name and good energy, we talked a little, then we said ” bye” and that was it for the day. Then the next day we said hi, started small talk and I asked her for her number and she told me she had kids and a boyfriend. I’m a bit confused too because I thought she was picking on me or was she really picking on me and telling me about the kids and the boyfriend so I wouldn’t be surprised in the future? What do you think? p.s. I am 22 years old. I don’t know her age because it’s not fair to ask, but she’s definitely older than me.
