I'll keep it as brief as I can. Been with DH for years; marriage has always been up and down. We have kids, both work FT, stressful jobs. DH has new job. He loves it and has been working pretty much 7 days a week, whilst I deal with all the domestic stuff, the kids and working FT. New job involves occasional travel. Recently he went on a trip but did not mention that it was with colleagues, and so I assumed he was going alone. He called me when he was away and still didn't mention any colleagues but he did make a point of saying that he had forgotten his travel adapter plug. At the time I advised him to ask hotel staff or go try to buy one. Today I saw a hotel room receipt for a twin bedded room and I asked him if he was with a colleague and he then told me he was with a female and a male colleague but that he did not share his hotel room. He was prickly in his tone. In terms of the plug adapter thing why ask hotel staff when you could just ask your colleagues? I probably sound paranoid and, in fairness to him, in the early days of our relationship I definitely had my moments of being jealous. However, there is a flip side to this too there was an incident some years ago in which he went on a business trip and ended up totally unnecessarily sharing a hotel room with a female colleague and he lied to me about it. I forgave him at the time but have never forgotten and, quite honestly, I don't 100% trust him. Anyway I know that there was no male colleague on this trip. It's possible that he as lied because he's trying to avoid upsetting me or the like. I accept that his job will involve travel with female colleagues but quite honestly I feel really disrespected by him.
