Wife and co-worker text sweet dreams every night... too flirty? Possible cheating?

Anonymous
She and her coworker constantly text each other short messages throughout the day. When they wake up they say good morning, when they go to bed she'll say "sleepy time" (that's MY saying to her), then good night and sweet dreams. Nearly every day.

I just discovered this on accident on her new phone, she knew I was playing with the old phone and has already deleted her entire text convo with him, so I can't go back more than a month. However, I know she's been giving him a ride to and from work once in a while. They've also stopped by the grocery store or gone out for an after work meal (she'll sometimes bring me something home).

I don't mind her having a close guy friend, but she never mentions me in her texts with him, but she does to her other close guy friend whom I know she has no interest in (because she calls him her little brother). Her texts are also sometimes flirty, like "let's go to sleep now" his response "in my bed?" her response "wink smiley". WTF... there's a couple more instances, like calling each other "love" once, and her also saying "I like you". When we were on vacation, she didn't even mention me when he asked what she was up to, she said "Came back from the hot tub, just got out of the shower." That is too much info in my opinion.

I am so upset that I don't even feel like talking to her, leaving the house. I'm not going to confront her but I will be watching closely for sure signs. But... am I reading too much into this?

So far, it seems I am right to be suspicious. Should I confront her... or gather solid evidence for divorce first?

I parked down the street from his house to see if she would pick him up, but I was spotted. He texted her and she called me asking "what's going on?" I didn't admit anything, eventually she says "if you're trying to accuse me of something, I'm going to be really mad" "I have to deal with people at work accusing me because I gave him a ride to work sometimes, it's stupid and pissing me off" I just replied "... ok".

She doesn't seem to be trying very hard to defend herself, nor prove her feelings.
