Have been OLD. Met a guy, started messaging 3 months ago. Met up about 10 weeks ago. We started sleeping together a month ago. Went for a weekend away last weekend. He's been a bit cold this week in that he hasn't been messaging as often as usual. He's had a lot on at work, so I was fine with that. We messaged Thursday morning (just, morning how are you? Have a good day etc). Didn't hear anything else all day. Messaged him yesterday morning to see if he wants to meet on Sunday. He hasn't read it or replied. Should I message again? Wonder if I'm being ghosted.
