Should I ignore her or still try to be friends?

I have a neighbor who has a son a few months older than my son. We hit it off we all moved into the neighborhood about the same time (me subdivision built) I always tried to reach out to her and see if we can arrange play dates. Most of the time she ghosts me. She won’t respond to my texts even when I texted happy Mother’s Day! A month or two later she texted me asking if I could watch her son for a few hours. I had to work so I couldn’t. Well the times when I’ve been outside walking with my son she doesn’t even turn around or acknowledge us 🧐 yesterday I got a fb invite to her sons bday and I really wanna go bc i want my son to have buddies in the neighborhood plus I remember her saying her son doesn’t have any cousins or anyone close in age to play with. And today she texts me asking if I can baby sit her son at 2:30 I work 6-2:30 so with traffic and picking up my son I won’t be back home until after 3-3:30. I can get off early and try to get here on time but my husband said I shouldn’t be going out of my way to help her out when she has been ghosting me and is just using me. But also I don’t have many mom friends and I’m lonely so I don’t want to mess up becoming friends but then again how can we be friends if she treats me this way? Maybe I just overreacting and being hormonal lol
