Im not sure what to do...

You know, for the sake of $100 he could have found a room of his own and made you a whole lot more comfortable with the situation Grrrr. 

Sounds like he was a bit passive-aggressive upon his homecoming.  Is this his usual behaviour?  I had many previous relationships that were passive-aggressive and all the ultimatims and bluff-calling totally totally did my head in. 

I was thinking about this... and the more I think about it, the more I don't understand the lady's original argument. How can one 'feel safer' with a married man than a single man? It takes two to tango... even if one of the single blokes put the moves on her it's easy enough to say 'get the hell out'. And if the chap involved didn't take no for an answer, that's rape... and I don't know the stats or anything, but I kind of figure that rapists could be married too, if you're that perverted a wee thing like wedding vows aren't going to stop you... so I don't get her initial argument anyway.

Whatever the truth of the matter is, im sorry you are going through it , being pregnant is already an emotionally trying time , and this is the last thing you need

If its bugging you that much why not write down what bothers you and why it bothers you and then ask your DH if you can have a civil conversation where you BOTH listen to each other.. no getting defensive and no getting angry and see if you can sort it out.

At least if you have written it down beforehand you have worked through what bugs you and you can bring it up without the defensiveness and anger etc. When either of you get into that frame of mind you won't have a productive conversation.

If you leave it as is your mind could create things that aren't there, it will get possibily blown out of proportion in your own head and the tense feelings won't just go away. Ya know?

Oh wow, thats awful. I have been in a relationship where after I caught him out I was always looking for 'signs' which I didn't want to ever do again.

I know where DP is at all times (at home) his phone, the car is both ours, all his accounts we know each others passwords etc, I have never had a reason to ever think he would cheat or has done that before, just this trip has be totally baffled! I don't believe he would jeoperdise our family but in the same sense, this whole drama makes none!!

I was wondering if I was creating an issue out of nothing (those preggy hormones) as I have been upset about alot of things lately. But I just wonder what her intentions are I guess and why he just didn't tell her to p!ss off. Which when reading Emz, perhaps its lack of attention on my part so he liked having to "look" after her.

But he knows, that if I ever find out more happened I definately won't be sticking around to give second chances or work things out.

Grrr trust me, from experience, you want to talk about this ASAP so you don't get things going around in your head.

After Dh and I talked, it was clear that he'd felt pushed aside by my pregnancy and our son being in hospital (which to me is a fair enough reason lol) but he needed to realise as well that had he communicated better, it wouldn't have been an issue. It wasn't until we actually figured that out, that we could relate to each other.

The good thing I read from one of your posts is that he didn't hide his phone. DH would take his even to the shower with him - the first night he didn't, I looked through it (hey not proud of it but I don't care anymore) and found the woman's number as 'security'. It came in handy when DH went missing and my MIL called her house and ended up talking to DH. Btw he wasn't having a physical relationship, but she was milking his breakdown for all it was worth and it wasn't until he found out she'd been telling me they were sleeping together and she was trying to get pregnant that he snapped out of his insanity and realised she had her own agenda. Women are b*tches, this one got burnt by her partner so she decided noone else had the right to be happy.

Good luck, please talk to your partner, actually, listening is better. If it takes going to the court counselling, do it. It's free and even just one session can help you communicate a lot more (FWIW, my DH and I are over everything, completely besotted with each other again and happier than we have been in a couple of years, and no trust issues anymore, so it can have a happy ending ) - if he is in fact getting some comfort from this woman, he may just be having a bit of a PMS moment

I'm suspicious by nature, and here's my take on him telling you that she has had a mental breakdown... That if he tells you beforehand that she's a bit crazy, it's insurance that if anything ever comes out later (perhaps from her)... then maybe you won't believe it because he has given you something to think she is not credible in what she says.

On the plus side, he isn't hiding his phone.. One thing my cheating ex did was hide his phone at all times..

The most important thing I ever learned from my past experience is to DEFINITELY trust your instincts.. You'll be amazed at how accurate they are, and if something doesn't seem right, it isn't..
To what extent, I guess that's another issue, but it's clear that something is going on that you need to get to the bottom of or it will keep eating away at you and your relationship.
