I know age is just but a number but our 7-year gap is scaring me

I am 25 and have been dating this lady for about three months now. She is beautiful and has always seemed to be a young girl from her size and looks and this is what attracted me to her. I pursued her and now we are in this relationship but I have now realised that she is 32 and has two children probably from different fathers. She keeps insisting that she is madly in love with me and that we would make a good family together. I have feelings for her but don't know what to do in light of what I know about her now. Please advise me.
