My last thread: www.mumsnet.com/Talk/relationships/3968267-Was-he-cheating?pg=2 explains everything. He left for a bit but has came back saying nothing happened, he’s sorry for the lack of attention etc and I thought it was going ok until he went out with his friend to the ‘pub’ on Saturday, when he got about (around 2:30am) I saw some messages on his phone to friend he was supposed to be out with. He’d sent him 5 voice notes at around 1am-1.30 which I thought was strange considering he was supposed to be with him. I didn’t get chance to listen as he came back in the room. Around 9ish in the morning his friend left him a voicemail which my OH deleted along with the voice notes. Also his friend posted the same night he was meant to be with OH on Instagram he was driving a car (I had no idea he drove) with someone else in the car and no mention on OH. Last night I found that back in feb he had downloaded on his old phone an app called ‘secret photo/video’ and one disguised as a calculator that was called ‘secret apps’. I’ve had his mum messaging me saying my suspicion and paranoia are splitting our family up. I need proof Aibu to follow him on his next night out?
