Girls, would you date your sister's ex?

So long story short I very recently got involved with my sister's ex. They broke up a few months ago and were living together he was supporting her financially. They were together around 5 years or so. We have been talking for about 2 months and just met up over the weekend. He's 39 and wants to see me regularly and exclusively and has offered a lot of things.

No offensive replies please they will be ignored.
