My wife says she is straight but I think she is cheating on me with her rounders teammate

DEAR DEIDRE: IS my wife cheating on me with her rounders teammate?

We’re both 41 and have been together for ten years.

Recently my wife has started hanging out with her rounders teammates, some of whom are bisexual.

She joined the team after a pal asked her along and I’ve hardly seen her since.

She’s out every night with this group, and there’s one older woman who she speaks to every day.

My wife insists they are just friends, but she never stops talking about her.
