I have a few ideas. First is an ex line, I have two exes with a clear backstory for him, one would be from when he was about 18/19 years old and the other would be from about 8 years ago. If neither of those appeal, they could always have been set up on a blind date that went terribly wrong late last year when he was briefly divorced from his wife. There are also a few other lines where either could fit that are less defined: female best friend or coworker (he's a police sergeant). If none of those appeal, his wife ~rilez is looking for friends and I believe she has a specific line for a 35+ woman - I could be remembering wrong, but if you would like to know that let me know and I will get her linked to this post!
