1 of 2 owners no longer responding, do I contact other owner?

[Shawn Hershberger]

I hand wrote yellow letters to a house near me and got a call from the owner last September (he owns the property with his ex wife). He said he was interested in selling and I got into the house to look around and work up an offer. Owner lives out of state. House needs a lot of work, water damage, new roof, landscaping, etc. 

I made him an offer and we would communicate every 2 weeks or so. I haven’t heard from him in about 2 months after a couple attempts. When I originally mailed letters last year, I mailed to his ex wife because they had different last names. I recently got a call from his ex wife who found one of my letters. 

Not sure what do here. The owner I’ve been communicating with no longer gets back to me, and I now have a new outlet with the other owner. Should I call the ex wife back and explain where we are? I highly doubt she knows how bad the house is. There’s potentially $20-40k profit if price is right? Any suggestions??
