Like Ronni i have no issue in general with age gaps either. My last husband was 19 yrs my junior. Despite how that went, the problems were not age related. And i wouldn't just on the basis of age advise anyone to pursue or decline the opportunity to 'date' someone.
In this case the more relevant issues in the info you've presented us with are the red flags:
Her 'pursuing' you, instead of flirting and getting you to do the asking first. If she's consciously running a long con--she's not very bright about it. Some people do it unconsciously, because of their own issues/needs.
Her telling you about her bad marriage and 4 kids before you've even expressed an interest in dating her? Unless she told you this cause you asked to know more about her, this could be a play for sympathy, to appear 'vulnerable'. Especially if you met where she works. The info about the kids should have come out in a natural way when a date was getting scheduled. ie "I have to find a sitter." Which opens the door for you ask 'how many, how old?'.
Years ago there was a Pop psychology concept, which had some merit: The 'Dance Away Lover'. This is the person who not only tells you they love you quickly, in the first days, weeks, months (however long it takes for you to believe it and emotionally invest in relationship with them) they think everything about you is 'perfect', they bend over backward to agree with and accommodate you. Once you invest/commit to relationship---suddenly they find fault with traits they found endearing initially. This is not the normal healthy openness about things that annoy one from the get go but we overlook till we realize we may have to live with certain habits the rest of our lives. This is a tactic that is never deployed till the pursued party is 'hooked'. The fault-finding puts the target on the defensive, and in many cases makes them afraid they'll 'lose' the pursuer. This is why they wait till you've expressed your strong feelings in return, because otherwise you might decide they are not worth the effort.
i hope you'll take everyone's comments under advisement, even if you're 'looking' for female companionship and that's been complicated by the Pandemic.
Somebody says they 'love' me that soon, before an actual 'date' even --- my response would be "You don't know me near well enough to love me, so what you love is an idea of me you have. When i don't fit the idea well enough---you'll be mad at me not yourself. So, no thanks!"
