Long one, sorry. I posted at the time but had it pulled as I'd given too much away at a vulnerable time. Huge thanks for all previous support.
Some outcomes...
After weeks of protestations and I don't knows DP has admitted that he was aware there was something amiss with the way he was texting his new female friend (more regularly than any other contact bar me and his best friend, me not knowing about her beyond absolute basics given a long time ago when they first met and with no idea as to their closeness which he ended up concealing).
We have recently had a very calm talk through it all because I do want to work through it. This is the first time we have had a situation remotely like this in all our long relationship and I don't think I can leave him over texting. It hadn't escalated to anything more than the regular secret text chatting (nothing dirty) but as previous posters pointed out it sounded like a possible early stages EA and needed addressing regardless due to secretive and cagey behaviour. She is someone he sees on person every day anyway hence the excessive/intimate nature of bolting a very regular, evening and weekends texting relationship on top of that behind my back. Here are a few of his insights:
PROS
- he initially didn't tell me about her or their closeness because he is a man of few words anyway. Initially she had been a welcoming friendly face who had put him (nervous person) at ease. But he was aware she had become a go-to evening and weekends chat person very quickly and without my knowledge. By the time he realised it was something that needed outing he felt it was a bit late and he was scared about how to broach it as he knew that I would likely (and rightly) be concerned at the meaning behind the volume and regularity of texts and him having not kept me in the loop. He was worried about me saying 'she obviously fancies you and you're going along with it'. So he buried his head in the sand. He admits being a coward. (Please note I have NO history of paranoia or jealousy regarding female friends, he has several and I have a few close male friendships too).
- I pressed him about when/why he realised there could be an issue. The bit that felt off to him was the regularity and sudden go-to-ness of her, but he says he rationalized this as okay because he was so keen to make friends since his recent life change and she is talkative and friendly. And each individual message itself was 'safe' so when he checked in with himself it was easy to say nothing was wrong -- there was no over the top flirting or intimacy so texting could continue and I didn't really need to know, it was probably fine, just chat.
- He didn't dial it back after his own "realisations" and moments of questioning because he convinced himself he was doing/had done nothing wrong and to change his behaviour would have been to admit wrongdoing and make it real/make it a thing and he didn't want it to be a thing.
- He didn't know what was in it for her (which he admits is an issue but the uncertainty also let him continue to an extent as it wasn't definitely wrong) but he was apparently so certain in himself that it wasn't about fancying her or not loving me that he again managed to rationalise it to himself (we have now had the chat about how feelings can develop unexpectedly in intense/secretive relationships and he understands this was naive and risky.)
- He knows it was wrong to keep it from me and admits being a coward who thought he could just ignore the issue until it hopefully went away (which is stupid but not malevolent, I think?).
- He definitely loves me and definitely doesn't fancy her. (I can confirm she is not his type physically). It was more of an attention/validation thing, something to do/an opportunity to come across well in a new context but boundaries got blurred because he hadn't paused to consider where they should be.
- She did invite him to meet her to spend time together for a hobby just the two of them but he turned this down as he didnt want to go. It seems he knew this might have been going a bit too far (though he is still unsure of her intentions and still wants to think it has all just been plain friendly). He says he just didn't want to go point blank and wouldn't have accepted the invite from anyone else either.
CONS
- Apparent lack of self control: he says he realised after an evening spent texting her when I was out with the girls that maybe the situation needed reigning in. He proudly stated to me last night that this is when he decided he wasn't going to continue. I checked my calendar and then his phone and pointed out that he texted her again 2 days after that (admittedly in a more perfunctory way but certainly still while I was elsewhere and in a way that led to more chat). In a sense it seems he couldn't help himself and so despite his own realisations I'm not sure what would ever have been enough for him to stop of his own accord or bring this up with me, two things he claims he would have done eventually. I'm certain he wouldn't have as the two of them were only going to get closer as time went on and he already couldn't broach it with me. He agrees that he was perhaps on a slippery slope here (but still maintains no romantic interest in her).
- the absolute mess of it: it has taken weeks and several strops and arguments for this to come out so plainly. It has been like blood from a stone. The hobby/day out invite was only revealed to me last week. There was a lot of denial and self delusion it seems, with me being dragged along behind. This latest frank chat is the result of me saying look, this has gone on too long and I can't function in this relationship anymore. It was jump or be pushed.
So wise MN, what do you make of this and would you give it a go or LTB? I am wanting to work through it and he seems willing, even with therapy if needed, but I also want a reality check on the gravity of my decision.
