I've been seeing someone for 4 months. All going well, getting along good, stayed at each others' places and all fine. No major red flags, only what I kind of perceived as a minor one, maybe not even.... after two months of dating, we slept together. We're not exactly physically compatible but decided to give it time... that's not the red flag though...... his Whatsapp pings almost every night around 11, then 11.30, then midnight.... then around 1 am. Every night without fail someone is messaging him really late. He's dead to the world and doesn't hear it.
I asked him about it and he was evasive, brushed off my concerns if you like. I decided to let it go and mind my business but to keep an eye on things. Last weekend we went on a short break and rented an Air BnB. On the last morning, I left him asleep upstairs and went down to make tea. When I brought it up, he was awake and looking at his phone, but when I walked in his face looked shocked and he turned the phone face down and pushed it under the covers. I said nothing, nipped back downstairs to get something and when I went back into the bedroom he was back on the phone. Not a problem but this time he looked so guilty and quickly pushed it back under the covers again. He seemed incredibly flustered.
I didn't bring it up until later on that day when I got back home as I was tired and upset. I texted him and asked him why he felt the need to push the phone under the duvet twice when I walked in, that it's odd behaviour and could he please explain it to reassure me in some way, as it was bringing up my older concerns about the late night messages... which by the way are STILL happening.
I have never snooped. I was tempted to but never did. A mature adult should, in theory, explain the odd behaviour and attempt to provide reassurance.
Instead, he has read my messages and completely ignored the question.
I know it's not looking good but I'd like to hear what people have to say about it.
