I've never been able to catch the multiple texting so I don't really know what level relationship their at. The ones I have seen are random mundane stuff. She texted him once in the middle of the night telling him she was drunk. That kind of stuff. But, why is she doing that?
I do know that one day they both got off work early(they work together). They had drinks at a bar near work. I texted him and called him to tell him that I was getting off work early too. I wanted to meet him somewhere. He ignored my calls/text. I saw his phone later and put 2+2 together. I asked him about it but he said it was nothing. Again with the lesbian thing. I suspect that he's been out with friends and she's joined them. Since I know of calls to her at times that he was out with the guys.
Since his declaration of love, relationship-wise things have been good. We spend time together, go out. But, I had detached the level that I'm not fully invested in our marriage, sort of self-protection mode. I told him I'd have to see serious work on his part before I could fully reinvest in us. I don't know if I ever can.
