Is this suspicious? Tell me if I’m being crazy

So I’m 20, and my coworker is probably about 45. She has a known thing for younger guys, which is not a problem at all. However what is a problem, is that I think she’s trying to sleep with my 22 year old boyfriend. We’ve never had any issues before, her and I always joke around at work and help each other out! But I got into work the other day and she asked me if my boyfriend was available to help her put up a volleyball net for her daughters. I didn’t think anything of it initially, she’s super small so she probably genuinely does need help with it, and my boyfriend is tall and strong and he just helped us move the location of our job. What put me off was that she then asked me if I would be working on Saturday (which I am), what time I get off, and how old he is. Now I don’t really see a need for her to ask those? It just seemed out of place to me.
