Is he or isnt he?

[SurelyNotAgain]

I might be totally paranoid but have recently been starting to wonder if DH is playing away? Totally based on lack of sex - we have only had it once this year which is unusual as i only have to flash my boobs and he's up for it. No more arguments than normal and no other suspicious behaviour.

So is he having a bit on the side, what do i need to look out for?

thanks to everyone who has replied, am going to have an early night and try to get a good nights sleep. It has helped just writing this down to get some perspective on it.

I discovered my H had an affair 6 months ago with a work colleague. I came on here to ask for advice a month before I found out as things were not "quite right", but he refused to say what despite me asking pleading
The red flags (in my case) were refusing to discuss my worries and making me out to be paranoid. Distancing himself from me and being grumpy/argumentative, complaining of being tired and going to bed with his phone (said phone aquiring new password/lock) or staying up late to watch crap TV that he knew I wouldn't want to watch, so I would go upto bed. Not initiating sex (but wanted hugs/to be held), Improved hygiene & dressing smarter for work. Talking about X and how funny/smart she was then not mentioning her at all (rememebered this sometime after). Coming home slightly later than usual (hour at the most) once a week and suddenly the dog needed long walks early morning and last thing at night instead of the usual run about in the field opposite the house. All so he could text X, the physical stuff took place after work in that hour. No nights away or unexplained days off/absences. It took me 4 long weeks to get the answer I didn't want.
The best advise I got was to trust my gut.... and snoop

The usual signs are being distant and critical, possessive with mobile/laptop, and appearing stressed. Is he spending lots time time spent in the bathroom with the mobile?

Its hard to tell if something is really going on so I would keep a close eye and do some snooping if you can.
