it depends on how patient and understanding you are, how much she is actually telling you, and if you like children. She could be the girl of your dreams? Give it a try if it seems like too much just be honest and tell her it isn't for you.
Age is nothing but a number. It's all about how mature you are and she is. You have to keep in mind she has a child. If you want someone who will party all the time with you - then she's not the girl for you. If you aren't serious about this relationship and you aren't in it long term then do yourselves both a favour and don't start something. You both have to think of this child before you think about your own needs and wants. But if you honestly feel like you're ready to be in a serious, committed adult relationship where instead of partying you're doing family- like things then I say go for it.
It is very difficult to go your separate ways if need be the child may grow attached to you or you to him. My grandson is in this type of relationship Drama all the time, he doesn't want to hurt the children they love him so much but their relationship is not all that good. Be careful and good luck he is 20 she is 28
