Is my DO having an affair?

[brightside20]

Hello all.

Going through DP phone tonight.

Came across a conversation between them and a long time mutual friend.

They have been talking everyday. 100s of messages.
Some of them are about me. And how awful I am.
Messages about their weekly coffee meet ups.
Multiple kisses on every message.
He's sending a good morning message everyday.
Silly names for each other again used everyday.
Inside jokes.
Some flirty banter etc.

They have similar interests etc. So am I reading too much into this?

TIA. Don't know what to think and panicking.

Yes it’s odd these just friendships never happen with other blokes isn’t it. My dh hardly speaks to anyone on the phone and only does when he has to yet the phone bill showed numerous hour long conversations he’s the same with text but yet hundreds to the ow. He can’t even say it’s a male female thing as he isn’t like that with his other female friends either

Even if it isn't a physical affair, those messages alone would be enough for me to LTB. I'm sorry, you must feel like absolute shit, I know I would.
