Has my OH met somebody else

[FordFairlane]

My OH has been unhappy for many years of which I take responsibility, it was my DS birthday yesterday and she kicked me out, then she told me I was unable to leave for another week. This morning she text me at 7.40am having started work at 7 informing me she was leaving tomorrow as she has somewhere else to stay, she has previously told me she made an emotional connection with a colleague?

The only way to know for sure is to ask her (unless you can get access to her phone to check texts, calls, emails, social media private messages etc)
