You might try sending her a dozen long stemmed red roses into which floral arrangement has been inserted a cruise ticket and a short note accompanied by your recent picture. Of course you run two definite risks:
1. of probably either hearing from an irate husband
2. or worse (if you have my luck), picking up the phone only to hear your old flame laughing hysterically and saying, "You have GOT TO BE KIDDING ME!"
It's a helluva gamble there, kid. But whay the hay, why not give it a try?
